a horse exerts a pull on a cart of 300m so that the horse-cart system moves with a uniform speed of 18km/hr on a lebel road. calculate the power developed by the horse in watt and also find its equivalent in horse power

Open in App

Solution

Force by horse, F = 300 N
Speed of the cart, v = 18 kmh^-1 = 5 ms^-1
Power used by the horse to maintain this speed is, P = F.v = 300 Ã— 5 = 1500 Watt
1 hp = 745.7 W
Therefore, the power in hp is, P = 2.01 hp

When a horse exerts a force on cart , the cart exerts an equal and opposite force on the horse. Then how come the horse can manage to pull the cart ?

A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton's third law the cart must then exert an equal and opposite force on the horse. Since the two forces are equal and opposite, they must add to zero, so Newton's second law tells us that the acceleration of the system must be zero and therefore no matter how hard the horse pulls, it can never move the cart.

Q. When a horse pulls a cart, the force that helps the horse to move forward is the force exerted by

Q. Consider a cart being pulled by a horse with a constant velocity. The horse exerts force
