Take a full mock →Q1 · Force and Laws of Motion · MEDIUM
A cricket ball of mass 0.15 kg is moving with a velocity of 20 m/s. A batsman hits the ball and it moves back in the opposite direction with a velocity of 30 m/s. What is the magnitude of change in momentum of the ball?
Q2 · Force and Laws of Motion · EASY
According to Newton's first law of motion, an object will continue to be in its state of rest or uniform motion in a straight line unless acted upon by an external force. This property of the object is called:
