A bicyclist comes to a skidding stop in \(10\) m. During this process, the force on the bicycle due to the road is \(200\) N is directly opposed to the motion. The work done by the cycle on the road is:
1. \(+2000\) J
2. \(-200\) J
3. zero
4. \(-20000\) J
1. | zero | 2. | \(-\frac12mu^2cos^2\theta\) |
3. | \(-\frac12mu^2sin^2\theta\) | 4. | \(-\frac12mu^2\) |
