Question

A 5 kg block is placed on a horizontal surface. A force of 10 N is applied to the block. The coefficient of friction between the block and the surface is 0.2. Find the acceleration of the block.

• A. \( 0.04 \, \text{m/s}^2 \)
• B. \( 1.0 \, \text{m/s}^2 \)
• C. \( 2.0 \, \text{m/s}^2 \)
• D. \( 1.5 \, \text{m/s}^2 \)

Hint:

The frictional force always opposes the motion of the object and reduces the effective applied force. Make sure to account for friction when calculating the net force.
