Given: m = 10 kg, u = 10 m/s, Retarding force F = 0.1x J/m. Find acceleration a.

1. 95 m/s
2. 90 m/s
3. 85 m/s
4. 80 m/s

Correct answer: 90 m/s

Solution

The retarding force is given as F = 0.1x J/m, which implies work done per unit displacement. Using F = ma, and equating it to the given force, we can solve for acceleration. The correct answer is 90 m/s.
