Question
A block of mass 5 kg is on a rough horizontal surface and is at rest. Now a force of 24 N is imparted to it with negligible impulse. If the coefficient of kinetic friction is 0.4 and g = 9.8 m/s2 , then the acceleration of the block is :
- 0.26 m/s2
- 0.39 m/s2
- 0.69 m/s2
- 0.88 m/s2
The correct answer is: 0.88 m/s2
