-a- Given Force on the cycle due to the road- 200 N and distance traveled during skidding before stopping -10 mWork done - force-xD7-displacement-200-xD7-10-x2212-2000J -negative sign used as applied in the direction opposite to that of motion-xA0- -xA0-b- zero

A cyclist comes to a skidding stop in $10 m$ . During this process, the force on the cycle due to the road is $200 N$ and is directly oppose to the motion.
(a) How much work does the road do on the cycle?
(b) How much work does the cycle do on the road?

(a) Given Force on the cycle due to the road= 200 N and distance traveled during skidding before stopping =10 m
Work done = force $\times$ displacement
=200 $\times$ 10= $- 2000 J$ (negative sign used as applied in the direction opposite to that of motion
(b) zero

(a) Given Force on the cycle due to the road= 200 N and distance traveled during skidding before stopping =10 mWork done = force×displacement=200×10=−2000J (negative sign used as applied in the direction opposite to that of motion (b) zero
