Given coefficient of kinetic friction is zero and the coefficient of restitution is e:

A particle of mass m, collides at an angle (theta), with speed v, onto an infinite mass horizontal surface.
Collision time is 0.2 seconds.

What is the horizontal distance travelled by the particle during the collision?

Since no horizontal force acts on the particle, the horizontal component of its velocity remains constant.
