A ball of mass 0.442 kg moving east (+x direction) with a speed of 3.72 m/s collides head-on with a 0.221 kg ball at rest. Assume that the collision is perfectly elastic.
a) What is be the speed of the 0.442-kg ball after the collision?
b) What is be the direction of the velocity of the 0.442-kg ball after the collision? to the east or to the west
c)What is the speed of the 0.221-kg ball after the collision?
d)What is the direction of the velocity of 0.221-kg ball after the collision? to the east or to the west
Answers
For perfect elastic collision linear momentum and totat kinetic energy remains constant (conserved).
