Question

#1) A large truck with mass m1 pushes a disabled small truck with mass m2<m1, giving it a forward acceleration a. Each vehicle exerts a force on the other as a result of their interaction. which vehicle exerts the greater force on the other?

a) the car

b) the truck

c) both force have the same magnitude

d) the car does not exert any force on the truck

#2) In the situation described in problem 1), what is the magnitude of the force F that the car exerts on the truck?

a) F=ma          b) F=m2a          c) F=(m1+m2)a               d) F=0                  e) -m2a                f) other(specify)

3) State the law or the principle to use to find the force F in problem 2).

Explanation / Answer

1. c) same force (by newton's 3rd law)

2. b) since the acceleration of car is the imparted acceleration so F= m2*a

3. 2nd law. F=ma
