A tow truck exerts a force of 2000N on a car, causing it to accelerate at $4 \mathrm {~m} / \mathrm { s } ^ { 2 }$ . What is the mass of the car?
A) 500kg
B) 750kg
C) 1000kg
D) 1500kg
E) None of the above

Using Newton's second law, $ F = ma $, where $ F $ is the force, $ m $ is the mass, and $ a $ is the acceleration. Rearranging for mass, $ m = \frac{F}{a} = \frac{2000 \, \text{N}}{4 \, \text{m/s}^2} = 500 \, \text{kg} $.
