Given:

A 0.8-kg car that travels over a hill (parabola). When the car is at point a, it is traveling at 9 meters per second. Its acceleration is 3 m/s^2. The force that it needs is represented by this equation:

F = ma

where F is the force
m is the mass of the car
a is the acceleration of the car

F = 0.8 kg * 3 m/s^2
= 2.4 N
