A ball of mass 0.2 kg moves with a velocity of 20 m/sec and it stops in 0.1 sec; then the force on the ball is:
A cannon ball of mass 2 kg is fired at a target 500 meters away. The 400 kg cannon recoils with a velocity of 2ms−1. Assuming cannon ball moves with constant velocity, when will it hit the target?
A cannon ball (mass = 2 kg) is fired at a target of 500 meters away. The 400 kg cannon recoils with a velocity of 2 m/s. Assuming cannon ball moves with constant velocity, when will it hit the target?
