Que1.Consider two balls of identical mass. If ball 1 is moving to the right towards stationary ball 2 at 1.0 m/s and the two balls collide elastically, what will the final velocities of both balls be? (Hint: consider this simulation.)

Que 2.If the same two balls again undergo a collision, but this time the collision is inelastic, what will the final velocities of both balls be?

Que 3.What are the conditions for elastic and inelastic collisions?

Que 4.Explain how the acceleration of an object can be equal to gravitational acceleration.

1. A billiard ball moving at 5.80 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.81 m/s at an angle of 34.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. (a)magnitude_____ m/s (b) direction_____ ° (with respect to the original line of motion) 2. A rod of length 36.00 cm has linear density...

Two small, identical steel balls collide completely elastically. Initially, ball 1 is moving with velocity v1 directly toward ball 2, and ball 2 is stationary. After the collision, the final velocities of ball 1 and ball 2 are, respectively A) v1 / 2; v1 / 2 B) v1; 2v1 C) -v1; 2v1 D) 0; v1 E) -v1; 0

A moving ball (ball #1) makes a perfectly elastic collision with a stationary ball (ball #2)....

A moving ball (ball #1) makes a perfectly elastic collision with a stationary ball (ball #2). After the collision it is observed that the speed of ball #2 is five times that of ball #1. Determine the angles θ1 and θ2 that the two balls scatter as measured from the initial direction of ball #1. You may assume that the two balls have identical masses, and you may need the identity sin2(x) + cos2(x) = 1. Please explain any concepts...
