A ball of mass m moves with speed `v` and it strikes normally with a wall and reflected back normally, if its time of contact with wall is `t` then find force exerted by ball on wall

A ball of mass m moves with speed v and stricks a wall having infinite mass and it returns with same speed then the work done by the ball on the wall is

A ball of mass m moves with speed v and stricks a wall having infinite mass and it returns with same speed then the work done by the ball on the wall is

A ball of mass 500 gram strikes a wall with a velocity of 80 m/s and rebounds with the same velocity. If the tme of contact is 1/30 sec, then the force exerted by the ball on the wall is

A ball of mass 250 g moving with 20 m/s strikes a vertical wall and rebounds along the same line with a velocity of 15 m/s. If the time of contact is 0.1 s, the force exerted by the wall on the ball is

Choose the correct options A ball of mass 250 g moving with 20 m//s strikes a vertical wall and rebounds along the same line with a velocity of 15 m//s . If the time of contact is 0.1 s, the force exerted by the wall on the ball is
