A person weighing 68 kg is pulled out of the hole by a horse at a speed of 4 km / h Determine the horse’s power.

To determine the horse’s power value, we will use the formula: N = F * V = m * g * V.

Constants and variables: m is the mass of the person pulled out of the pit (m = 68 kg); g – acceleration of gravity (g = 9.81 m / s2); V is the lifting speed of a person (V = 4 km / h = 1.111 m / s).

Calculation: N = m * g * V = 68 * 9.81 * 1.111 = 741 W.

Answer: The horse’s power is 741 watts.
