How would you expect a 150g ball to move if it was used in this experiment?
At t = 0.30s a baseball has a velocity of (7.35m/s, 6.86m/s). At t = 1.3s its velocity is (7.35m/s, -‐2.94m/s). Find the magnitude and direction of the average acceleration vector. Given: vox = 7.35m/s, voy = 6.86m/s, vx = 7.35m/s, vy = -‐2.94m/s, and ∆t = 1.3-‐0.3 = 1.00s.
How do you calculate the force needed to throw an object?
Multiply mass times acceleration. The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration.
How much force does it take to throw a ball?
I’ll just tell you the answer is about 13 pounds of force. For a batted ball, the change in velocity is twice as big for the reasons explained earlier, and the time is about 0.0007 seconds.
What is the acceleration of a ball with a mass of 0.40 kg is hit with a force of 16n?
a = F m = 16 0.4 = 40 m/s 2 .
How is projectile motion determined?
The time for projectile motion is completely determined by the vertical motion. So any projectile that has an initial vertical velocity of 14.3 m/s and lands 20.0 m below its starting altitude will spend 3.96 s in the air.
What happens when you throw a ball?
An object that is thrown, kicked or otherwise launched through the air is called a projectile. When a projectile is moving through the air, however, it is subject to the force of gravity, which causes it to move down toward Earth. It is also subject to the force of air resistance, which slows the projectile down.
What is the acceleration of a softball if it has a mass of 0.50 kg and hits the catcher’s gloves with a force of 25 N *?
The acceleration is 50 m/s2 .
How do you calculate force in physics?
Force Equation. \\( F = Ma \\) Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.
How do you calculate the maximum impact force?
The formula can easily be extended to calculate the approximate maximum impact force (a.k.a. peak impact force) by multiplying the resulting average impact force by two.
What is the F average and F maximum impact force of 180 kn?
Replacing in the formula we get F avg = 0.5 · 2400 · 7.5 2 / 0.75 = 90 kN and a maximum impact force of 180 kN. ( calculation link)
How do you calculate kinetic energy from mass and velocity?
Kinetic Energy. In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.
