A constant net force along the motion acts on a 6 kg object for 5 s, increasing its velocity from 3 m/s to 8 m/s. What is the force magnitude?

Explanation

The acceleration is (8 − 3)/5 = 1 m/s². For constant mass, the net force is F = ma = 6 × 1 = 6 N. The calculation assumes the given force is the net force along the motion.
