Question

The brakes on a bicycle apply 125 N of frictional force to the wheels as the bicycle travels 14.0 m. How much work have the brakes done on the bicycle?

Answer 1

Hope this answer is correct

Sorry for any error

Step-by-step explanation:

work done by the breaks os WORK = FORCE X DISTANCE

so work = 125 X 14 =1750 joule

Answer 2

Answer: 1750 J

Step-by-step explanation:

• Given, force applied by the brakes on the wheel is 125 N.
• Distance covered after the brakes are applied is 14 m.
• We know that work done is the product of force and displacement.
• Work done= Force × Displacement

                          =125×14

                          =1750 Nm

                          =1750 J

• Hence, the work done by the frictional force on the bicycle is equals to 1750 J.
