Position Velocity and Acceleration

You may use a calculator for both problems. Show all of the necessary work. Use proper mathematical notation. 2001 AB3. A car is traveling on a straight road with velocity 55ft/sec at time t=0. For seconds, the car’s acceleration a(t), in , is the piecewise function defined by the graph above. Is the velocity of the car increasing at t=2 seconds? ................
