Question

The following 2 questions refer to the col-
lisions between a car and a light truck whose
weight is equal to that of the car (M = m).
For each description of a collision below,
choose the one answer from the possibilities
that best describes the size (or magnitude) of
the forces between the car and the truck.
Assume: Friction is so small that it can be
ignored.
They are both moving at the same speed
when they collide.
1. The car exerts a greater amount of force
on the truck than the truck exerts on the
car.
2. Not enough information is given to pick
one of the answers.
3. Neither exerts a force on the other; the
car gets smashed simply because it is in the
way of the truck.
4. None of the answers correctly describes
the situation.
5. The truck exerts the same amount of force
on the car as the car exerts on the truck.
6. The truck exerts a greater amount of force
on the car than the car exerts on the truck.

part b:
The light truck is standing still when the car
hits it.
1. None of the answers correctly describes
the situation.
2. Not enough information is given to pick
one of the answers.
3. The truck exerts the same amount of force
on the car as the car exerts on the truck.
4. The car exerts a greater amount of force
on the truck than the truck exerts on the car
5. Neither exerts a force on the other; the
car gets smashed simply because it is in the
way of the truck.
6. The truck exerts a greater amount of force
on the car than the car exerts on the truck.

Explanation / Answer

what ever may be the situation of collision between car andtruck, the force exerted by car on the truck will be samethat of the truck on the car, according to Newtons third law ofmotion (as we ignored the friction) part a : option 5 part b: option 3
