One horsepower is equal to 735 watts. What is the maximum speed the cart can travel

One horsepower is equal to 735 watts. What is the maximum speed the cart can travel if the horse pulls it with a force of 50 N?

N = 735 W.

F = 50 N.

V -?

Power F is called a scalar physical quantity that shows how quickly mechanical work A.

Power N is determined by the formula: N = A / t, where t is the time for performing mechanical work A.

Mechanical work A is determined by the formula: A = F * S, where F is the force that acts on the body, S is the movement of the body under the action of the force.

The ratio of the traversed path S to the time of its passage t is called the speed of movement V: S / t = V.

N = F * S / t = F * V.

V = N / F.

V = 735 W / 50 N = 14.7 m / s.

Answer: the maximum speed of the cart is V = 14.7 m / s.
