Step 1
Step 1: Work done is given by the formula W = F * d * cos(theta), where F is the force, d is the displacement, and theta is the angle between the force and displacement vectors. Show more…

A bicyclist comes to a skidding stop in $10 \mathrm{~m}$. During this process, the force on the bicycle due to the road is $200 \mathrm{~N}$ and is directly opposed to the motion. The work done by the cycle on the road is $(\mathrm{A})+2000 \mathrm{~J}$ (B) $-200 \mathrm{~J}$ (C) Zero (D) $-20,000 \mathrm{~J}$
A bicyclist comes to a skidding stop in $10 \mathrm{~m}$. During this process, the force on the bicycle due to the road is $200 \mathrm{~N}$ and is directly opposed to the motion. The work done by the cycle on the road is $\quad$ [NCERT Exemplar] (a) $+2000 \mathrm{~J}$ (b) - $200 \mathrm{~J}$ (c) zero (d) $-20,000 \mathrm{~J}$
