A Horse Exerts a Pull on a Cart of 300 N So that the Horse-cart System Moves with a Uniform Speed 18 Km/H on a Level Road. Calculate the Power Developed by the Horse in Watt and Ain Horse Power.

Question

A horse exerts a pull on a cart of 300 N so that the horse-cart system moves with a uniform speed 18 km/h on a level road. Calculate the power developed by the horse in watt and also find its equivalent in horse power.

Numerical

Solution

Given force F = 300 N, u = 18 km/hr

Now, power = `"W"/"t" = "F.s"/"t"` = F.v

or P = 300 x `(18 xx 10³)/(60 xx 60)` = 1500 watt

Now 1 H>P = 746 watt

1500 watt = 2 H>P (approx)
