CAIE A-Level Physics AS 3.1.4 Force As Rate of Change of Momentum Questions question 1

[Maximum number: 1]

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.
