Question

The brakes on a bicycle apply 95 N of force to the wheels. When the
brakes are applied, the bicycle comes to a stop in 16 m. How much work
are the brakes doing on the wheels?
0 1,500
O 250 m
1,520 J
40 m/s

Answer 1

Answer:

Work done, W =1520 J

Explanation:

We have,

The brakes on a bicycle apply 95 N of force to the wheels. When the  brakes are applied, the bicycle comes to a stop in 16 m.

It is required to find the work done by the brakes on the wheels. We know that the product of force and displacement is equal to the work done. It is given by :

$W=Fd\\\\W=95\times 16\\\\W=1520\ J$

So, the work done by the brakes is 1520 J.
