A car is stopped at a traffic light. The light turns green, and at time t = 0 the car starts moving and travels with a constant acceleration. At that instant a truck traveling at a constant velocity is alongside the car, where each vehicle is positioned at x = 0. The truck passes the car, but the at later catches up to the truck in front of a house, such at time t = D, the front of each vehicle is positioned at X = D. How would a velocity graph of both vehicles look like?

Two cars travel in the same direction along a straight highway, one at a constant speed of 55 mi/h and the other at 70 mi/h.

(a) Assuming they start at the same point, how much sooner does the faster car arrive at a destination 10 mi away?

(b) How far must the faster car travel before it has a 15-min lead on the slower car?

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.
