when a bus stops, 60000 J of work is done by the brakes in a time of 7s. calculate the power of brakes

(Please add with solutions)


Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The power of an object doing a work W in a given time t is given by

[tex]\boxed{P = \frac{W}{t}}[/tex]

where:

P = power

W = work

t = time

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for P

[tex]P = \dfrac{W}{t}[/tex]

[tex]P = \dfrac{\text{60,000 J}}{\text{7 s}}[/tex]

[tex]\boxed{P = \text{8,571.43 W}}[/tex]

Therefore, the power of brakes is 8,571.43 W.
