1. (25 pts) To try to win the $25 first place prize in South Park’s annual sled competition, Cartman
has constructed a $15,000 rocket sled. He is doing a test run down Main Street to see how well
it works. As the rocket engine fires and he sleds towards downtown, the sled has a constant
acceleration for 10.0 seconds until the engine shuts off. At that moment, a parachute deploys,
which begins slowing the sled at a rate of 4.0 m/s2. Exactly 15.0 seconds after the rocket sled
started moving, Cartman passes in front of the City Wok restaurant, 950 meters from his starting
point.
(a) (15 pts) What was the acceleration of the rocket sled for the first 10 seconds, while the engine
was on? (Hint: it may be helpful to draw a plot or two.)
(b) (10 pts) Cartman is unaware that Officer BarBrady is outside City Wok, measuring the speed
of cars passing by, just as they pass in front of City Wok. The speed limit by the restaurant
is 45 mph. The penalty for speeding is $50 for every 5 mph over the speed...
