A cheetah starts from rest, accelerates to its maximum speed (we'll assume the acceleration is constant during that time), then runs at its maximum speed for a little while, then collapses from exhaustion. Assume that the cheetah is moving in the positive x direction. In each of the following questions, you'll identify which graph goes with which quantities (and you are allowed to use the same graph more than once).

A driver uniformly accelerates his car such that a=6.851im/s2. a. Assuming he starts from rest, find the velocity of the car after it has accelerated for 4.55 s. b. If immediately after that 4.55 s the driver lays off the accelerator, slams on the brakes, and comes to a stop in the subsequent 5.62 s, what is the acceleration he experiences during that time, assuming the acceleration is constant?

Art and physical endurance enthusiasts compete in an annual race called the Kinetic Sculpture Grand Championship (A kinetic sculpture is a sculpture that is able to move). Let's suppose a kinetic sculpture team races its vehicle on a river. It takes 0.05 hours for the vehicle to race down the river going with a current of 3 miles per hour, and 0.15 hours to travel the same distance back up the river against the current. a. Set up a linear system of equations for this problem where d represents the distance traveled and x represents the rate at which the kinetic sculpture is moving. b. Find the rate at which the kinetic sculpture was moving down the river and back.

What is the magnitude of the average acceleration of the car while it is slowing down? Express your answer in feet per second squared. b. With this same average acceleration, how much longer would it take you to stop? c. What total distance would you travel from when you first apply the brakes until the car stops? Express your answer in feet.
