a) Two cars are set to race, one can only accelerate at a rate of 2m/s starting from rest, and the other can only travel at a set speed of 10 m/s. How fast does each car cover 400 m? Which car would cover a distance of 400 m faster?

b) If both cars from the previous question started from the same position, at what time would they have the same displacement? What is the displacement of the vehicles?

c) A truck covers 40 m in 8.5 seconds while smoothly slowing down at a constant rate ( acceleration is constant) to a final speed of 2.8 m/s. Solve for the truck's original speed and it's acceleration.

d) You are cruising at a speed of 60 mph (26.8 m/s} when a deer appears 100 m ahead of you. What is the maximum time you have to stop and what acceleration do you need to have to avoid hitting the deer?

Suppose the two cars had rubber bumpers in the front and back – similar to the bumper cars children (of all ages!) ride at amusement parks. Also, suppose that the cars are sturdy enough that the metal they are made of does not bend during the collision. In this case, the cars would undergo a perfectly elastic collision. Assume just like in the first collision question that the SUV (initially moving to the right) collides into the stationary smart car....
