A person holding a rifle (mass of person and rifle together is 100 kg) stands on a smooth surface and fires 10 shots horizontally, in 5s. Each bullet has a mass of 10 g with a muzzle velocity of 800 `ms^(-1)`. The final velocity acquired by the person and the average force exerted on the person are

A person holdinga rifle (mass of person and rifle together is 100kg) stands on a smooth surface and fires 10 shots horizontally, in5s. Each bullet has a mass of 10 g with a muzzle velocity of 800 ms^(-1).The final velocity acquired the person and the average force exerted on the person are:

A rifle man, who together with his rifle has a mass of 100 kg, stands on a smooth surface and fires 10 shots horizontally. Each bullet. has a mass 10 g and a muzzle velocity of 800 m//s , a. What velocity does the rifle man acquire at the end of 10 shots? b. If the shots are fired in 10 s , what will he the average force exerted on him? c. Compare his kinetic energy with that of 10 bullets

A rifle man, who together with his rifle has a mass of 100 kg, stands on a smooth surface and fires 10 shots horizontally. Each bullet. has a mass 10 g and a muzzle velocity of 800 m//s , a. What velocity does the rifle man acquire at the end of 10 shots? b. If the shots are fired in 10 s , what will he the average force exerted on him? c. Compare his kinetic energy with that of 10 bullets

A person of mass 40 kg standing on a smooth horizontal plane of ice throws a body of mass 10 kg with a velocity 8ms^(-1) . Then the total kinetic energy of person and body is

A bullet of mass 10 g is fired with a velocity of 100 m/s from a rifle of mass 2.5 kg, the recoil velocity of the rifle is

A bullet of mass 10 g is fired with a velocity of 100 m/s from a rifle of mass 2.5 kg, the recoil velocity of the rifle is

From a rifle of mass 4 kg, a bullet of mass 50 g is fired with an initial velocity of 35 ms^(-1) Calculate the recoil velocity of the rifle.
