A man of mass `40kg` is at rest between the walls as shown in the If `'●'` between the man and the walls is `0.8` find the normal reactions exerted by the walls on the man .

A man of mass 40 kg is at rest between the walls as shown in the figure. If between the man and the walls is 0.8, find the normal reaction exerted by the walls on the man. (g = 10 ms^(-2) )

A man of mass 40 kg is at rest between the walls as shown in the figure. If mu between the man and the walls is 0.8, find the normal reactions exerted by the walls on the man.

A ball of mass 0.5 kg moving with a velocity of 2 ms^(-1) strikes a wall normally and bounces back with the same speed. If the time of contact between the ball and the wall is one millisecond, the average force exerted by the wall on the ball is
