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.

What is the equation for throwing a ball?
You throw a ball into the air from a height of 5 feet with an initial vertical velocity of 32 feet per second. Use the vertical motion model, h = -16t2 + vt + s where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball.
How do you calculate how far you can throw something?
The formula for the distance is d = v² * sin(2α) / a. Launch velocity or thrown distance can be calculated from the other three values. Example: a stone, thrown with 70 kilometers per hour, can fly up to 38.5 meters. But thrown at a 30 degrees angle, it flies only 33 meters.
How do you solve a falling object problem?
What is the G value when an object is thrown down?
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth).
How do you solve projectile motion problems?
What is the acceleration when you throw a ball up?
When you throw a ball up in the air, its speed decreases, until it momentarily stops at the very top of the ball’s motion. Its acceleration is −9.8 ms−2 at the very top since the body is moving upward against the gravity. In other words, the acceleration due to gravity g=9.8 ms−2↓.
What happens when you throw a ball in the air?
Analyzing motion for objects in freefall For example, when a ball is thrown up in the air, the ball’s velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.
How do you find the height of an object thrown upward?
How do you throw a ball to the maximum distance?
If there were no air resistance, you would get the maximum distance by throwing at a 45° angle (Figure 3). But there is air resistance, and the faster the ball is thrown, the more air resistance there is. Also, the longer the ball is in the air, the more time there is for air resistance to slow down the ball.
How far can a human throw a ball?
The average person can throw a baseball up to 90 feet. This distance is determined by how far you can throw the ball with proper form and power. The average person can throw a baseball up to 90 feet.
How do you find the energy of a thrown object?
Potential energy with respect to gravity is PE = mgh. When the object is dropped, thrown downward or projected upward, its kinetic energy becomes KE = mv2/2, along with a factor of the initial velocity. The sum of the PE and KE is the total energy, which is a constant.
Which falls first the heavier or lighter object defend your answer?
Heavier objects hit the ground first as they have very less air resistance.
Do heavier objects fall faster?
Given two objects of the same size but of different materials, the heavier (denser) object will fall faster because the drag and buoyancy forces will be the same for both, but the gravitational force will be greater for the heavier object.
Does throwing an object down increase acceleration?
Hence, dropping an object down does not increase acceleration. Q. When an object is dropped from a height, it accelerates and falls down. Name the force which accelerates the object.
When an object is thrown downward What is its acceleration?
An object in free fall experiences an acceleration of -9.8 m/s/s. (The – sign indicates a downward acceleration.) Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s/s for any freely falling object.
Why acceleration is taken as negative when object is thrown upwards?
So, if an object is moving vertically upwards, the direction of motion is positive for upwards journey. Hence, the acceleration due to gravity is taken as negative as its direction is downward. Was this answer helpful?
What is the formula for free fall?
The formula for free fall: Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= frac12gt^2. v²= 2gh.
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 are the 3 types of projectile motion?
- Oblique projectile motion.
- Horizontal projectile motion.
- Projectile motion on an inclined plane.
How do you solve projectile motion problems without angles?
What is the velocity of an object thrown up?
When you project an object upward and release it at its initial velocity, it is moving in the opposite direction of the force of gravity. Thus the initial velocity is negative. The velocity of the object is also negative on the way up but positive on the way down.
When a ball is thrown upward What is its velocity at its highest point?
Therefore, velocity at the top is zero and acceleration is acceleration due to gravity (g). Was this answer helpful?
When you throw something upward it will always go down?
This is because the gravitational force of earth pulls the object towards it.
What kind of force is applied when throwing a ball?
A contact pull and friction. A contact force is when two interacting objects are physically touching, for example: when you are throwing a ba throwing a ball you are using a contact force.
