Gravity causes vy to change as the banana travels. Set up Gizmo: Acceleration is a change in velocity.
Why should you aim directly at the monkey?
You should aim directly at the monkey because the monkey and the banana will fall with the same acceleration, and therefore will intersect (if the angle and velocity allow the banana to reach the tree).
Does the bullet hit the monkey?
Yes, the bullet will hit the monkey. As at the same instant when the hunter fires the bullet, the monkey also drops. Now both, bullet and monkey will experience the same downward acceleration due to gravity ‘g’.
What is the equation for projectile motion?
The equation for the distance traveled by a projectile being affected by gravity is sin(2θ)v2/g, where θ is the angle, v is the initial velocity and g is acceleration due to gravity. Assuming that v2/g is constant, the greatest distance will be when sin(2θ) is at its maximum, which is when 2θ = 90 degrees.
Do both the monkey and the banana experience the same acceleration?
Both banana and monkey experience the same acceleration since gravity causes all objects to accelerate at the same rate regardless of their mass. Since both banana and monkey experience the same acceleration each will fall equal amounts below their gravity-free path. Thus, the banana hits the monkey.
Does the banana hit the monkey if you aim straight at it?
As is obvious from the animation above, the banana moves in a straight line path in the absence of gravity. As such, a banana aimed directly at the monkey will hit the monkey.
What does the phrase shoot a monkey mean?
shoot a monkey: phrase used when one is mad; equivalent to ADamn [email protected] short bus is comin= for you: you=ve done something really stupid. Derives from the minibuses used to transport the mentally challenged.
What will be the value of Vy when the ball is at the top of its trajectory?
At the peak itself, the vertical velocity is 0 m/s; the velocity vector is entirely horizontal at this point in the trajectory.
What is the formula of time of flight?
Time of flight t ( v 0 sin θ 0 − g t 2 ) = 0. Ttof=2(v0sinθ0)g. T tof = 2 ( v 0 sin θ 0 ) g . This is the time of flight for a projectile both launched and impacting on a flat horizontal surface.
What launch angle will yield the longest drive?
A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.
How do you solve a projectile problem?
What are the 3 equations of motion?
- First Equation of Motion : v = u + a t.
- Second Equation of Motion : s = u t + 1 2 a t 2.
- Third Equation of Motion : v 2 = u 2 + 2 a s.
What are the 4 equations of motion?
The equations are as follows: v=u+at,s=(u+v2)t,v2=u2+2as,s=ut+12at2,s=vt−12at2.
What refers to the amount of motion an object has?
momentum. physics term; it refers to the quantity of motion that an object has. Momentum can be defined as “mass in motion.” …Momentum depends upon the variables mass and velocity. Momentum is a measurement of mass in motion: how much mass is in how much motion.
How do you solve a monkey problem?
“Keeping fruit and other food concealed when monkeys are about and keeping doors and windows shut are some of the ways to stop monkeys from entering the house,” said Smit.
What are the two components of a projectile’s motion?
There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately.
What does walking in high cotton mean?
“They’re living in high cotton,” – meaning their lives are pretty cushy and they’re doing well. Or “I’m feeling low cotton today,” meaning I’m having a bad day. ( Leslie Criss – Tupelo Mississippi)
What does I wish cotton was a monkey mean?
This phrase comes from a more renowned Little Rascals episode, where the Rascals are rubbing a magic lamp and wishing various things; including a large watermelon. A street vendor hears Stymie wishing for the melon and rolls one down the sidewalk — VOILLA! The lamp works!
What does a cotton picking minute mean?
The expression what a cotton picking minute means Hold on for a damn moment! It shows anger or other strong feelings, and cotton picking is a substitute for stronger curse words. It may have racist connotations for some.
What is the acceleration of the ball during the entire time the ball is in the air?
The cause of the ball’s acceleration is gravity. The entire time the ball is in the air, its acceleration is 9.8 m/s2 down provided this occurs on the surface of the Earth. Note that the acceleration can be either 9.8 m/s2 or -9.8 m/s2.
What is the velocity of the ball just before it hits the ground?
Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward. Notice the figure above has the positive y direction upward.
Why is the vertical speed zero at the peak of a projectile’s flight?
As the projectile moves upwards it goes against gravity, and therefore the velocity begins to decelerate. Eventually the vertical velocity will reach zero, and the projectile is accelerated downward under gravity immediately.
Which has the longest time of flight?
What is the longest flight time in the world? The longest nonstop commercial flight in the world is scheduled at 18 hours and 50 minutes from Singapore (SIN) to New York City (JFK) serviced by Singapore Airlines.
Does time of flight depend on angle?
The time in air is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the time in air.
Why is 45 degrees not the best launch angle?
A launch at 45 degrees would allow the ball to remain in the air for a longer time, but it would then be launched at a lower horizontal speed at the start and it would slow down more because of the longer flight time.
