To settle an argument Dr Goulding and his Mrs (his wife) decide to have a 40.0 m lang snowshoe race, with the prize being a very nice locally made face mask. At the start line they shake hands and when their cat helper Charlie fires the start gun they begin running on thier snowshoes. Dr Gaulding reaches his maximum speed of speed of 2.68 m/s in a time of 10.0 s while The Mrs accelerates to her maximum speed of 3.00 m/s at a rate of a,-0.20 m/s2 How far are they apart when the runners have both reached their maximum running speeds?

When last we left our friend Wile E. Coyote (SuperGenius), was peeling himself off a canyon wall and none the worse for wear. This time, he has obtained an Acme^ TM rocket-powered dragster with the AcmeTM Premium Parachute Braking System (patent pending)Starting from restthe dragster accelerates at a constant rate of 36.4 m/s ^ 2 for 14 seconds. At this point, the coyote realizes that he has passed the Road Runner and so he instantly cuts off the engine and deploys his braking system - which doesn't work. He therefore travels an additional distance of 1800 m at constant velocity until again becoming one with a canyon wall. Determine: (a) The total time for Wile E. Coyote's motion described above; on (b) The total distance covered by Wile E. Coyote's motion described above ; (c) The average velocity for Wile E. Coyote's motion described above.
