A car and a truck are on the highway. Both need to accelerate at 7 m/s2
in order to avoid an accident.
a. Find the force acting on the car, which has a mass of 408 k
b. Find the force acting on the truck, which has a mass of 2,100 kg.

Fnet(t) = m(t)a. YOu know the acceleration its a basic math question from here.
a=7m/s/s
m(t)=2100kg
m(t)*a = 14,700N is the Force on the Truck
