# The first meters of a 100-meter dash are covered in 2 seconds by a sprinter who starts from rest and accelerates with a constant acceleration. The remaining 90 meters are run with the same velocity the sprinter had after 2 seconds.

The first \(10 \, \text{meters}\) of a \(100 \, \text{meter}\) dash are covered in \(2 \, \text{seconds}\) by a sprinter who starts from rest and accelerates with a constant acceleration. The remaining \(90 \, \text{meters}\) are run with the same velocity the sprinter had after \(2 \, \text{seconds}\).

**Part a)** Determine the sprinter’s constant acceleration during the first \(2 \, \text{seconds}\) *(3 points)*

**Part b)** Determine the sprinters velocity after \(2 \, \text{seconds}\) have elapsed. *(3 points)*

**Part c)** Determine the total time needed to run the full \(100 \, \text{meters}\). *(3 points)*

**Part d)** Draw the displacement vs time curve for the sprinter. *(3 points)*
