A small motor does 3800J in 25 seconds. How much is the power done of the motor?
Explanation:
The power of an object, given the work W and the time t, is
[tex]\boxed{P = \frac{W}{t}}[/tex]
where:
P = power
W = work
t = time
———————————————————–
Solution:
Listing the given values
W = 3800 J
t = 25 s
[tex]\\[/tex]
Solving for P
[tex]P = \dfrac{W}{t}[/tex]
[tex]P = \dfrac{\text{3800 J}}{\text{25 s}}[/tex]
[tex]\boxed{P = \text{152 W}}[/tex]
[tex]\\[/tex]
Therefore, the power done of the motor is 152 W.
