in pedaling a bicycle uphill, a cyclist exerts a downward force of 500 n during each stroke. if the diameter of the circle traced by each pedal is 35 cm , calculate how much work is done in each stroke.



Answer :

175 Newton  work is done in each stroke.

we have given the data

force=500 newton

distance=0.35 m

now,

work done= force×distance

[tex][W=Fd],[=(500N)(0.35m)],[=175N][/tex]

  • When the force being applied causes motion, work is considered to have been completed. One example of effort being done against gravity is when a youngster kicks a ball into the air.
  • We are aware that Work done is equal to FS cos, where is the angle formed by the force's direction and the body's displacement. We only take into account the cosine component of the force, which indicates that we only take into account the force's component that is pointing in the direction of displacement.
