Question

a horse x** full on a card of 500 Newton so horse card system moves with a uniform velocity of 30 kilometre per hour what is the power developed by horse in what as well as in horsepower​

Answer 1

Power developed by the horse is 4165 watt and 5.58 horse power.

Given-

• Force exerted on the cart is = 500 Newton
• Uniform velocity of horse cart = 30 kmph = 30 × 1000/3600 = 8.33 m/sec

We know that power developed by the horse is

P = Work done / Time

Fs/t = Fv where s is the displacement and v is the velocity.

P = 500 × 8.33 = 4165 watt

To convert watt into horsepower

P = 4165/746 = 5.58 hp
