Question

a train moves in north direction with a speed of 54 km per hour and a monkey running on the roof of the train against its motion with a velocity of 18 km per hour with respect to the train then the velocity of Monkey as observed by a man standing on the ground is

Answer 1

Answer: 36 kmph  Explanation:  Given :  The velocity of the train set the ground = 54kmph   The velocity of monkey wrt train = - 18kmph( negative as the motion is in opposite direction)  We know that  V(mt) = V(mg) - V(tg)   Where V(mt) is the velocity of monkey wrt the train V(mg) is the velocity of monkey wrt the ground V(tg) is the velocity of train wrt the ground  V(mg) = V(mt) + V(tg)             = -18+54= 36 kmph   Therefore the velocity of monkey wrt a ground observer is 36 kmph in the direction of motion of the train , ( i.e) towards North direction.  Please mark as Brainliest.
