Question

An electric pulley system can perform 5.2 x 10 to the fourth power J of work in 60 seconds. What is the power of the pulley system?

Answer 1

Answer:

• 866.67 W

Explanation:

Power of the pulley system can be calculated by ,

• Power = Work done/time

Here we have,

• Work = 5.2 × 10⁴ J
• Time = 60 Seconds

Substitute the given values in the above formula,

• Power = 5.2* 10⁴/60
• Power = 866.67 W

Hence, The required power is 866.67 W
