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

Work done, W =1520 J

Step-by-step 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* 16\\\\W=1520\ J`

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