Question
A car of mass 500 kg is accelerating at 1.5 m/s². If the resistance to motion is 500 N, what is the force due to the engine?
Correct Answer
Option C is the correct answer.
Detailed Explanation
F_net = ma = 500 × 1.5 = 750 N. F_engine - resistance = F_net → F_engine = 750 + 500 = 1250 N.
Hint
F_net = F_engine - resistance = ma.
