Sally is driving along a straight highway in her 1965 Mustang. At t=0, when she is moving at 10 m/s in the positive x-direction, she passed a signpost at x=50 m. Her acceleration as a function of time is a=20 m/s^2-(0.10 m/s^3)t. Find her velocity and position as functions of time. Where is her velocity greatest? What is that maximum velocity? Where is the car when it reaches that maximum velocity?
