Question

How much power is generated by a motor that can do 3,000j of work in 75s

Answer 1

Answer:

40watts

Explanation:

Given parameters:

Work done  = 3000J

Time  = 75s

Unknown:

Power generated  = ?

Solution:

Power is the rate at which work is done;

       Power = $\frac{work done}{time}$

 Now, insert the parameters and solve;

     Power = $\frac{3000}{75}$   = 40watts
