Relative speed of two bodies moving in same direction with speed u and v m/s: where (u>v)

Relative speed of two bodies moving in opposite direction with speed u and m/s .

Relative speed of two persons moving with u m/s and m/s in same direction where u>V

Relative speed of two persons moving with u m/s and vm/s in opposite direction where u>v

A 60 kg body moving with speed 12 m/s collides inelastically with another body of mass 50 kg moving in same direction with speed 2 m/s. After collision the 50 kg body moves with a speed of 10 m/s. The value of coefficient of restitution (e) is :-

The relative velocity of two objects moving with same speed and in the same direction is

Two particles, of masses M and 2M, moving as shown, with speeds of 10m//s and 5m//s , collide elastically at the origin.After the collision, they move along the indicated directions with speeds v_1 and v_2 , respectively.The values of v_1 and v_2 are nearly :

Consider two point masses, m_1 and m_2 , moving along a straight line in the same direction with speeds u_1 , and u_2 . Let them undergo one-dimensional collision and retrieve each other with velocities v_1 and v_2 .how that ( u_1 - u_2 ) = - ( v_1 - v_2 ) i.e, after collision, their relative velocities are equal.
