A football player, starting from rest at the line of scrimmage, accelerates along a straight line for a time of 3 seconds. Then during a negligible amount of time, he changes the magnitude of his acceleration to a value of 1.1 m/secondssquared. With this acceleration, he continues in the same direction for another 2 seconds until he reaches a speed of 6.4 m/sec. What's the value of his acceleration (assumed to be constant) during the initial 3 sec period?

2. Relevant equations

kinematics

3. The attempt at a solution

I tried drawing a graph but to no avail. How would I do it with just equations?
