A young woman is pushing a baby carriage at a constant velocity along a level street. A friend comes by to chat and she lets go of the carriage. It rolls on for a bit, slows, and comes to a stop. On the graphs below, sketch qualitatively accurate (i.e., we don't care about the values but we do about the shape) graphs of each of the indicated variables. Take the positive direction as the direction she is walking. At time t = 0 she is moving with a constant velocity. At time t1 she releases the carriage. At time t2 the carriage comes to rest.

Draw the graphs of:

1) Position vs Time.
2) Velocity vs Time.
3) Acceleration vs Time.
4) Net force felt by carriage vs Time.
