In a solution, a board moving a velocity `v hati` w.r.t. earh, while a man a is running with a velocity `2vhati` w.r.t. earth and the man B is running with a velocity `-2vhati` with respect to earth. Both men are running from the opposite ends of the board at the same time as shown. Lenght of the board is L and they meet after time T, then

A boat is moving with a velocity 3 hati +4 hatj with respect to (d) ground, the water in the river is moving with a velocity -3 hati -4 hatj w.r.t. ground. The relative velocity of boat w.r.t. water is

A boat stems in a river with velocity 2hati + hatj with respecitve to the ground. The river water flows with a velocity -3hati - 4hatj with respect to the ground. What is the relative velocity of boat w.r.t river water ?

A trolley was moving horizontally on a smooth ground with velocity v with respect to the earth. Suddenly a man starts running from rear end of the trolley with a velocity (3//2)v with respect to the trolley. After reaching the other end, the man turns back and continues running with a velocity (3//2)v with respect to trolley in opposite direction. If the length of the trolley is L, find the displacement of the man with respect to earth when he reaches the starting point on the trolley. Mass of the trolley is equal to the mass of the man.

Choose the correct option: A trolley is moving horizontally with a constant velocity of v m//s w.r.t. earth. A man starts running from one end of the trolley with velocity 1.5v m//s w.r.t. to trolley. After reaching the opposite end, the man return back and continues running with a velocity of 1.5 v m//s w.r.t. the trolley in the backward direction. If the length of the trolley is L then the displacement of the man with respect to earth during the process will be :-

A trolley is moving horizontally with a constant velocty of v m//s w.e.t. earth. A man starts running from one end of the trolley with velocity 1.5v m//s w.r.t. to trolley. After reaching the opposite end, the man return back and continues running with a velocity of 1.5 v m//s w.r.t. the trolley in the baclward direction. If the length of the trolley is L then the displacement of the man with respect to earth during the process will be :-
