Question

A horse does 860 J of work in 420 seconds while pulling a wagon. What is the power output of the horse? Round your answer to the nearest whole number.

Answer 1

power = work x time

time = 420 / 3600= 7/60

power = 860 x 7/60

= 100.33Js

Answer 2

Answer:

★ Power output of horse = 2 watts ★

Step-by-step explanation:

Given:

• Work done by horse is 860J
• Time taken while pulling a wagon is 420 Seconds

To Find:

• Power output of the horse

Solutiob:

★ We know the formula that Power = Work done / Time taken ★

→ Power = $\large{\sf {\frac{</strong><strong>8</strong><strong>6</strong><strong>0</strong><strong>}{</strong><strong>4</strong><strong>2</strong><strong>0</strong><strong>}}}$

→ Power = 2.04 watts

† Converting to nearest whole number †

→ 2.04 → 2 watt

Hence, Power output of horse will be 2 watts
