A thin hoop with a moment of inertia 1/2mr^2 is rolling without slipping from The inclined plane whose height is h. Express the velocity of the hoop at the bottom of the inclined in terms of acceleration due to gravity and height of the inclined plane. . A 5 kg ball traveling East at 15 m/s hit a 10 kg ball moving at 5m/s towards West. After collision the 5 kg ball bounces back at 6 m/s. What is the...

Collisions and Kinetic Energy ** Two billiard balls are initially traveling toward each other with Ball 1 having a velocity of 2.00 m/s to the right and Ball 2 having a velocity of 8.00 m/s to the left. The balls undergo an elastic, head-on collision. Find their final velocities. (Define the positive direction to be to the right.) Part 1 + First consider two identical objects with equal mass, one is at rest and the other has a velocity of...

A 2 kg ball moving at 4 m/s to the right collides with a 3.0 kg ball moving at 2.0 m/s to the left. A) What is the total momentum before the collision? B) After the collision, if the first ball now moves at 1.2 m/s to the left, what is the momentum of the second ball? C) Then, using your answer for B, find the velocity of the second ball after the collision. (right is + left is -)...
Two balls with masses of 2.50 kg and 5.60 kg travel toward each other at speeds...
Two balls with masses of 2.50 kg and 5.60 kg travel toward each other at speeds of 14.0 m/s and 4.20 m/s, respectively. If the balls have a head-on inelastic collision and the 2.50-kilogram ball recoils with a speed of 8.40 m/s, how much kinetic energy is lost in the collision? A cue ball traveling at 0.80 m/s hits the stationary 8-ball, which moves off with a speed of 0.27 m/s at an angle of 31° relative to the cue...

8. (9 pts.) A 4.00-kg ball, moving to the right at a velocity of +2.00 mis on a frictionless table, collides head-on with a stationary 6.50-kg ball. Find the final velocities of the balls if the collision is completely inelastic (the balls stick together). 9. (12 pts.) A 2.5-kg ball and a 5.0-kg ball have an elastic collision. Before the collision, the 2.5-kg ball was at rest and the other ball had a speed of 3.5 m/s. (a) What is...

Two carts (one 1.3 kg, and the other 2.0 kg) roll without friction towards each other on a straight level track, and hit, and (thanks to some springy bumpers) bounce off of each other. The 1.3 kg cart was initially going 3.5 m/s in the positive x direction, while the 2.0 kg cart was initially going 4.7 m/s in the negative x direction. If after bouncing off of each other the 1.3 kg cart is going 1.2 m/s in the...
