A net force accelerates a 1200 kg car at 2.5 m/s^2. What is the size of the net force?
Answer and explanation
Correct answer: D. 3000 N
- Step 1: F = ma = 1200 x 2.5 = 3000 N. Answer: 3000 N. Why not the others: 480 N divides the mass by the acceleration, 1202.5 N adds them, and 30 000 N is out by a factor of ten.
