Question

A horse exerts a pull on a cart of 300 n. This makes the horse cart system move with a uniform speed of 18km/h on a level road.calculates the power developed by the horse in watt

Answer 1

HEY DEAR....!!

Force extended by a cart ,F = 300N

speed with which the horse - cart system is moving = 18km/hr = 18 x 10003600= 5m/s .

power developed by horse ,P = work done x time

f x S x t = fv
= 300 x 5
= 1500 w

power in term of horsepower = 1500746= 2.01 H. P...
