Question

a horse pulling a cart exerts a steady horizontal pull 300N and walks at the rate of 4.5km per h how much work is done by the horse in 5minutes​

Answer 1

Answer:

   W = 112.5 kN

Explanation:

   Now we have given that a horse pulling a cart exerts a steady horizontal pull of 300 N, so Force is 300 N.

   Distance travelled by horse in 5 minutes is:

                   4.5 x 5 / 60 = 0.375 km = 375 m

   Work done = Force x displacement

                   W = 300 X 375

                   W = 112500 N

                   W = 112.5 kN
