2- Two identical cars A and B are at rest on a loading dock with brakes released. Car C, of
a slightly different style but of the same weight, has been pushed by dockworkers and
hits car B with a velocity of 1.5 m/s. Knowing that the coefficient of restitution is 0.8
between B and C and 0.5 between A and B, determine the velocity of each car after all
collisions have taken place.
1.5 m/s
(a). Two identical blocks A and B are at rest on a frictionless plane. Block C of the same weight hits block B with a velocity of 2.5 m/s. Knowing that the coefficient of restitution is 0.7 between block B and block C and 0.4 between block A and block B.
(i) Determine the velocity of each block after all collisions have taken place.
(ii) From your working in Q1(a)(i), predict whether there will be another collision after block B collides with block A?
(iii) If the coefficient of restitution between block A and block B is changed to 0.7, explain with calculations whether there will be a collision between block B and block C after block B collides with block A?
The coefficient of restitution is 0.9 between the two 60-mm-diameter billiard balls A and B . Ball A is moving in the direction shown with a velocity of 1 m/s when it strikes ball B , which is at rest. Knowing that after impact B is moving in the x direction, determine (a) the angle 0, (b) the velocity of B after impact.
