Newton's second law says that force is equal to mass and acceleration . so the example ...

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car.ans=      F=ma                   F=1000 * 0.05
                   F= 50 newtons
