A long belt is moving horizontally with a speed of `5 km h^(-1)`. A child runs on this belt to and fro with a speed of `9 km//h` (w.r.t. bett) between his father and mother located `50 m` apart on the belt. For an observer on a stationalry plateform outsied, what is the
(a) speed of the chils runningin the derection of motion of the belt, (b) speed of thechaild runing opposite to thedirection of the belt, and (c ) time taken by the child in cases (a) and (b) ? Which of theanswers change, if motion is viewed by one of the parents ?gt

Ona long horizontally moving belt, a child runs to and fro with a speed 9 km h^(-1) (with respect to the belt) between his father and mother located 50m apart on the moving belt. The belt moves with a speed on the moving belt. The belt moves with a speed of 4 km h^(-1) . for an observer on a stationary platform outside, what is the (a) Speed of the child running in the direction of motion of the belt? (b) speed of the child running opposite to the direction of motion of the belt? (c ) time taken by the child in a and b? which of the answers after if motion is viewed by one of the parents?

On a long horizontally moving belt, a child runs to and fro with a speed 9 kmh^(-1) (with respect to the belt) between his father and mother located 50 m apart on the moving belt. The belt moves with a speed of 4 kmh^(-1) . For an observer on a stationary platform outside, what is the : speed of the child running opposite to the direction of motion of the belt.Which of the answer alter if motionis viewed by one of the parents ?

A train moves northwards with speed 80 km h^(-1) . While a car moves towards east with a speed of 60^( km h^(-1) , what is the velocity of the train w.r.t the driver of the car ?

A train 350 m long is moving at the speed of 20 km/h it will cross a man coming from the opposite direction at the speed of 1 km/h in:
