Carmela and desi leave their physics classroom separately and travel west. they both start from rest.desi leaves first traveling with an acceleration of 4 m/s2 west for the first 6 seconds and then he travels at a constant velocity. Two seconds after desi started, carmela begins with an acceleration of 3 m/s2 west for 10 seconds and after that she travels at a constant velocity.
Graph the velocity of both travelers as a function of time up to t=16 seconds starting at time t=0 when desi leaves the classroom. Use a solid line for desi;s velocity and a dashed line for carmelas velocity.
