Two persobns ech of mass m asere standing at the two extremes of a railroad car of mas M resting on a smooth track figure. The person on left jumps to the left with a horizontal speed u with respect to the state f the cr before the jump. Threafter, the other person jumps to the right, again with the same horizontl speed u with respect to teg state of the car before his jump. Find the vellcity of the car after both the person hae jumped off.

Two persons of mass m_(1) and m_(2) are standing at the two ends A and B respectively, of a trolley of mass M as shown. When both the persons jump simultaneously with same speed then:

Two persons of mass m_(1) and m_(2) are standing at the two ends A and B respectively, of a trolley of mass M as shown. When the person standing at A jumps from the. trolley towards left with u_("re1") with respect to the trolley, then

Two boys each of mass 40 kg are standing on the right side of a trolley of mass 80 kg , initially at rest on smooth floor. The boys jumps to the right with velocity 3 m//s with respect to the trolley before the jump. Find the final velocity of the trolley if the jumps : (a) together , (b) one after the other and (c ) one boy is on the left and the other on the right , the boy on the left jumps to the left and then the boy on the right jumps to the right. Each boy jumps with 3 m//s with respect to the trolley before the jump.

A man of mass m is standing on a plank of equal mass m resting on a smooth horizontal surface. The man starts moving on the plank with speed u relative to the plank. The speed of the man relative to the ground is
