What is head -on collision ?

The value of impact parameter in head-on collision is ......

A mass m_(1) moves with a great velocity. It strikes another mass m_(2) at rest in head-on collision. It comes back along its path with low speed after collision. Then

A particle moving with kinetic energy = 3J makes an elastic head-on collision with a stationary particle which has twice its mass. During the impact :-

A ball of mass m , moving with a speed 2v_(0) collides inelastically ( e gt 0) with an identical ball at rest . Show that (a) For head - on collision , both the balls move forward . (b) For a general collision , the angle between the two velocities of scattered balls is less than 90^(@)

Two balls of equal mass have a head-on collision with speed 6 m//s . If the coefficient of restitution is (1)/(3) , find the speed of each ball after impact in m//s

Statement I: No external force acts on a system of two spheres which undergo a perfectly elastic head-on collision. The minimum kinetic energy of this system is zero if the net momentum of the system is zero. Statement II: If any two bodies undergo a perfectly elastic head-on collision, at the instant of maximum deformation. the complete kinetic energy of the system is converted to' deformation potential energy of the system.

In case of head on collision, when the impact parameter is minimum theta =…………. Rad

An alpha particle of 10 MeV is moving forward fo a head on collision. What will be the distance of closest approach from the nucleus o atomic number Z = 29 ?
