Homework Help: Physics

Posted by StressedStudent on Saturday, September 15, 2012 at 4:47pm.

A heavy truck and a small car collide head-on. Before the collision they are going the same speed. Which of the following statements is true? (when I talk about the force and acceleration here I am talking about the *magnitude* -- don't worry about the direction, it's just what you think it should be).



The small car experiences a greater force than the truck and a greater acceleration.


The small car experiences the same force as the truck but a greater acceleration.


The small car experiences the same force and same acceleration as the truck.


The small car experiences a smaller force than the truck because it is smaller, but has the same acceleration.


The small car experiences a smaller force than the truck because it is smaller, but has a greater acceleration.


I do not know which answer it is and why
