Unformatted text preview: goes up in the second one without losing any speed at the bottom joint. Using the kinematic equations discussed in class, calculate how high will she rise in the right incline. Draw the y-t , v y-t graph for the child. Problem 2: A car is approaching a hill at 30.0 m/s when its engine suddenly fails, just at the bottom of the hill. The car moves with a constant acceleration of -2.0m/s 2 while coasting up the hill. (a) Write equations for the position along the slope and for the velocity as a function of time, taking x = 0 at the bottom of the hill where v i = 30 . 0 m/s. (b) Determine the maximum distance the car travels up the hill. Two other problems from book: Ch. 3: 3.32, 3.39;...
