Answer:
AnswEr :
The work done the road do on the cycle = 2500 Joules.
⠀
Explanation :
We are given with the displacement as well as force on the cycle due to the road, that is,
Displacement, s = 10 m.
Force, F = -250 N 〈opposite in direction〉
We have to find out the work done the road do on the cycle.
⠀_____________________
⠀
As we are given with displacement and force on the cycle due to the road..
⠀
We know that, if we are given with displacement and force on the cycle due to the road we have to required formula, that is,
⠀
⠀
→ W = Fs
⠀
⠀
Substituting the given values in the formula :
⇒ W = -250 × 10
⇒ W = -2500
⠀
【NOTE :- Negative sign indicates that teh work done is done in opposite.】
⠀
Hence, the work done the road do on the cycle is 2500 Joules.
⠀
⠀⠀⠀ Additional information :
Learn about work done :
Work done is the product of force and displacement.
Work done is represented as W.
The SI unit of work done is Joules (J).
The other units of work done is Foot-pound, Erg.
The derivations from other quantities are W = Fs and W = τθ.
