Web18 Nov 2024 · A physics student hurls a $315-g$ ball directly into a $3.54-kg$ box which is at rest on a table top. The baseball strikes the box with a pre-impact speed of $54.1 m/s$. … WebYou can model the bounce by updating the position and velocity of the ball: Reset the position to p = 0. Reset the velocity to the negative of its value just before the ball hit the ground. To account for energy loss, multiply the new velocity by a coefficient of distribution (-0.8).
