A ball of mass `1 kg` drops vertically on to the floor wit a speed of `25 m//s`. It rebounds with an initial velocity of `10 m//s`. What impulse acts on the ball during contact ?

A ball of 1 kg drops vetically on to the floor with a speed of 25 m s^(-1) . It rebounds with an initial velocity of 10 m s^(-1) . (a) What impulse acts on the ball during contact ? (b) If the ball is in contact for 0.02 s , what is the average force exerted on the floor ?

A 1.5 kg ball drops vertically on a floor hitting with a speed of 25 ms^(1) . It rebounds with an initial speed of 15 ms^(-1) . If the ball was in contact for only 0.03 , the force exerted on the floor by the ball is

A ball thrown vertically upwards with an initial velocity of 1.4 m//s. The total displcement of the ball is

A Rubber Ball Rebound A rubber ball of mass 2.0kg falls to the floor. The ball hits with a speed of 8m/s and rebounds with approximately the same speed. High speed photographs show that the ball is in contact with the floor for 10^-3s. What can we say about the force exerted on the ball by the floor?

A 1.0 kg ball drops vertically into a floor from a height of 25 cm . It rebounds to a height of 4 cm. The coefficient of restitution for the collision is
