3 Zero An object with a mass 10 kg moves at a constant velocity of 10 m sec A constant force then acts for 4 second on the object and gives it a speed of 2 m sec in opposite direction The acceleration produced in it is 1 3 m sec 2 3 m sec In the above question the force acting on the object is 1 30 N 2 30 N In the above question the impulse acting on the object is 1 120 newton x sec 2 120 newtont sec 3 30 newton x sec 4 30 newton x sec A machine gun is mounted on a 2000 kg car on a horizontal frictionless surface At some instant 3 0 3 m sec 3 3 N 4 4 0 3 m sec 3 N
