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

Two bodies of masses m and 2m are moving in same direction with speed 2v and v respectively just after collision body of mass m come to rest and body of mass 2m splits in two equal parts and move at 45^(@) from initial direction of body of mass m . Find out speed of one part after collision

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 :-

A particle of mass m moving in the x direction with speed 2v is hit by particle of mass 2m moving in the y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to:

When two bodies move uniformly towards each other, the distance between them decreases by 8 m//s . If both the bodies move in the same direction with the same speeds, the distance between them increases by 4 metre per second. What are the speeds of two bodies ?

If two train of length a metres and b metres are moving in opposite direction at u m/s and v m/s: then time taken by trains to cross each other.
