Question

A horse exerts a force of 200N to pull a cart. If the horse cart system moves with velocity 36kmh^-1 on the level road. Then find the power of the horse in term of horsepower.​

Answer 1

Answer:

F = 200N

v = 36 km/h

= 36×5/18 (to convert to m/s)

=10 m/s

P = F×v

=200×10

=2000 W

1 Horse Power = 746 W

thus,

2000 W = 2000/746

=2.68 HP

Here is your answer pal.

Answer 2

The power of the horse is approximately 2.682 hp

Given : A horse exerts a force of 200N to pull a cart. If the horse cart system moves with velocity 36kmh^-1 on the level road.

To find : The power of the horse in horsepower unit.

Solution :

We can simply solve this numerical problem by using the following process. (our goal is to calculate the power of the horse)

Now, We know that :

Power = Force × Velocity

Here,

• Power = 200 N
• Velocity = 36 km/h = 10 m/s

Velocity's unit conversion :

In 1 hour = 36 km

In 3600s = 36000 m

In 1s = 36000/3600 = 10 m/s

By, putting the available data, in the above mentioned mathematical formula, we get :

Power = 200 × 10 = 2000 N.ms⁻¹ = 2000 W

(As, 1 W = 1 N.ms⁻¹)

Now, converting the unit of power into horsepower unit :

1 hp = 745.7 W

or,

1 W = 1/745.7 hp

2000 W = 2000/745.7 = 2.682 hp (approx)

(This will be considered as the final result.)

Hence, the power of the horse is approximately 2.682 hp
