An electron (rest mass `=m_(0)` ) is moving with speed `v` so that its mass becomes `(5)/(3)m_(0),` then the value of `v` is

An object of mass m_(1) moving with speed v collides with another object of mass m_(2) at rest and stick to it. Find the impulse imparted to the second object.

A body of mass m_(1) moving with an unknown velocity of v_(1)hat i , undergoes a collinear collision with a body of mass m_(2) moving with a velocity v_(2) hati . After collision , m_(1) and m_(2) move with velocities of v_(3) hati and V_(4) hati , respectively. If m_(2)=0.5 m_(1) and v_(3)=0.5v_(1) , then v_(1) is :

A ball of mass M moving with speed v collides perfectly inelastically with another ball of mass m at rest. The magnitude of impulse imparted to the first ball is

A ball of mass M moving with speed v collides perfectly inelastically with another ball of mass m at rest. The magnitude of impulse imparted to the first ball is

A ball of mass M moving with speed v collides perfectly inelastically with another ball of mass m at rest. The magnitude of impulse imparted to the first ball is

A ball of mass m_(1) is moving with velocity 3v. It collides head on elastically with a stationary ball of mass m_(2) . The velocity of both the balls become v after collision. Then the value of the ratio (m_(2))/( m_(1)) is

A particle of mass m_(1) moves with speed v and collides head on with a stationary particles of mass m_(2) . The first particle continues to move in the same direction If (m_(1))/(m_(2)) is (e = coefficient of restitution )

A massive platform of mass M is moving with speed v=6ms^(-1) At t = 0, at body of mass m(m lt lt M) is gently placed on the platform. If c-efficient of friction between the body and platform is mu=0.3 and g=10 m//s^(2) , then

Three masses A, B and C are kept on a smooth horizontal surface as shown in the fiugre. A sharp impulse is given to the mass A, so that it starts moving towards B with speed v_(0) . What is the minimum value of m so that there is only one collision between masses A and B (all collisions are elastic)
