A car of mass M is movin with a uniform velocity `upsilon` on a horizontal road when the hero of a Hindi film drops himself on it from above. Taking the mass of the hero to bem what will be the velocity of thecar after the event?

A car of mass M is moving with a uniform velocity upsilon on a horizontal road when the hero of a Hindi film drops himself on it from above. Taking the mass of the hero to be m what will be the velocity of the car after the event?

a. A rail road car of mass M is moving without friction on a straight horizontal track with a velocity ct. A man of mass m lands on it normally from a helicopter. What will be the new velocity of the car? ltbgt b. If now the man begins to run on it with speed um with respect to car in a direction opposite to motion of the car, what will be the new velocity of the car?

A particle of mass m is projected with velocity upsilon making an angle of 45^(@) with the horizontal When the particle lands on the level ground the mag nitude of the change in its momentum will be .

The first ball of mass m moving with the velocity upsilon collides head on with the second ball of mass m at rest. If the coefficient of restitution is e , then the ratio of the velocities of the first and the second ball after the collision is

A bullet is fired with a velocity v from a gun of mass M. what will be the recoil velocity of the gun if the mass of the bullet is m ?

A truck, carrying sand, moves with uniform velocity u on a smooth horizontal road. If Delta m mass of sand falls in time Delta t from the truck, then to maintain the speed u, the truck needs a force
