1. A local amusement park learned that you successfully completed Dr. Whiteman's Coursera course on 2D Dynamics. They decide to hire you to redesign one of their rides. The ride consists of a passenger compartment on a rail. The passenger compartment is traveling 60 ft/sec on a straight rail. A stopping mechanism then applies a constant deceleration of 10 ft/sec² for a period of 5 seconds. At that point, the passenger compartment is given an immediate constant acceleration of 4 ft/sec². How long will it take for the passenger compartment to return to its original velocity of 60 ft/sec? Used with permission from "Engineering Mechanics: Dynamics," McGill/King, 4th Ed., 2003 10 seconds 12.5 seconds 15 seconds None of the above
