Question

A horse pull a cart with a force of 400N at an angle of 60^(@) with the horizontal at a speed of 18km/h .The power of the horse is​

Answer 1

Force applied = 400 N

Angle = 60⁰

Velocity = 18 × 5/18 ,= 5 m/s

To Find :-

Power

Solution :-

As we know that

\bf P = F \cos theta times vP=Fcosθ×v

W is the Work

F is the force

cos∅ is the ½

V is the velocity

\sf P = 400 \times \frac{1}{2} \times 5P=400×

2

1

×5

\sf P = 200 \times 1 \times 5P=200×1×5

\sf P = 200 \times 5P=200×5

\huge \mathfrak{P = 1000 \: Watt}P=1000Watt

Hence :-

Power of horse is 1000 Watt
