(b) Draw a ray diagram of formation of images by a convex lens.

A cricket ball of mass 100 g moving with a speed of 20 ms^(-1) is brought to rest by a player . Find the change in momentum of ball.

A bullet of mass 50 g moving with a speed of 300 ms^(-1) is brought to rest in 1 s . Find the impulse and the force .

(i) Two bodies have a mass ratio of 3:4 The force applied on the bigger mass produces an acceleration of 12ms^(-2) . What could be the acceleration of the other body, if the same force acts on it. (ii) A cricket ball of mass 100 g moving with a speed of 20ms^(-1) is brought to rest by a player . Find the change in momentum of ball.

When a ball of 0.5 kg mass moving with a speed of 20 ms^(-1) rebounds after striking normally a ferfectly elastic wall. Find the change in momentum.
