What force in Newton is required to accelerate a car starting from rest to 20 m/s in 15 seconds if the mass of the car is 2500 kilograms?

Answer:

F=m a,where m is the mass of the car and a is the acceleration.

The acceleration is a= dv\dt=70–30\10 =4 m\sec^2

So F=ma=2500 kg X 4 m\sec^2=10,000 kg .m\sec^2=10,000 N.
