HELP! Physics problem due tomorrow!!

## Homework Statement

A sports car can accelerate from rest to a speed of 40 m/s while traveling a distance of 200 m. Assume the acceleration of the car can be modeled as a decreasing linear function of time, with a maximum acceleration of 10.4 m/s^2. I must write equations for the acceleration, velocity and position of the car as functions of time.

Hi hmcaldwell01, Welcome to the Physics Forum.

While we can appreciate the urgency of your request, we can't help if you don't show any work.

It would be good to start with a picture of things and then attempt to write equations to stop the problem.

what does it mean to say the acceleration is a decreasing linear function? Does that mean the acceleration starts at 10.4 m/s^2 and then drops down to zero like the equation:

a= a_initial - k * t where k is to be determined
