9702Momentum and Newton’s laws of motion
A block is moving along a horizontal frictionless surface. A constant force F and a constant resistive force of 5.0 N act on the block as it is moving in the direction of the force F, as shown. The graph shows the variation with time of the momentum of the block. What is the magnitude of force F?
- A2.0 N
- B3.0 N
- C5.0 N
- D8.0 N
