What is the magnitude of the net force acting on a 2.0 X 103-kilogram car as it accelerates from rest to a speed of 15 meters per second in 5.0 seconds?

The net force on the car can be calculated using Newton's second law: F = ma where F is the net force, m is the mass, and a is the acceleration. The car accelerates from rest to 15 m/s in 5.0 seconds, so the acceleration is (15 m/s) / (5.0 s) = 3 m/s^2. Plugging in the values, we get F = (2.0 X 10^3 kg) * (3 m/s^2) = 6.0 X 10^3 N.
