Top View Two balls with masses m and 2m approach each other with equal speeds v on a horizontal frictionless table, as shown in the top view above. Which of the following shows possible velocities of the balls for a time soon after the balls collide?

This is because momentum is conserved in collisions when no external forces act on the system, as is the case here on a frictionless table. Show more…

Two balls (A and B) of equal mass approach each other with momenta of equal magnitudes and opposite directions. Half the total kinetic energy of the system is converted into thermal energy during the collision. The speed of ball B after the collision if the initial speed of ball A is 10.0 m/s, is closest to: 10 m/s 5 m/s 14.2 m/s 3.5 m/s 7.1 m/s none of the above

Ball traveling along a mat table with a speed of 5.0 m/s as shown; Ball B, which has the same mass, is initially at rest but is knocked off the table (1.5 m high) in an elastic collision with Ball A. Find the horizontal distance that Ball B travels before hitting the floor.

Billiard ball $A$ is moving in the $y$ -direction with a velocity of $2 \mathrm{m} / \mathrm{s}$ when it strikes ball $B$ of identical size and mass initially at rest. Following the impact, the balls are observed to move in the directions shown. Calculate the velocities $v_{A}$ and $v_{B}$ which the balls have immediately after the impact. Treat the balls as particles and neglect any friction forces acting on the balls compared with the force of impact.
