A force of 15 N, applied at to the horizontal, pulls a 5kg block on a smooth surface (friction is negligible).

Calculate the acceleration of the block. (4)

Thabo suggests that the force applied by the block on the surface is less than the weight of the block since the force is applied at an angle to the horizontal.

2. Is Thabo’s suggestion correct? Explain your reasoning. (2)

3. Calculate the normal force applied by the surface on the block. (3)
