(Constant Acceleration and the Equations of Kinematics) 3. (30 pts) Suppose that an automobile that is initially travelling at a velocity of 100.0 km/h is able to brake and come to rest in a displacement of 33.5 m. Assuming the acceleration is constant during braking, determine the automobile's acceleration using an appropriate equation of kinematics. Express your answer in units of m/sz. Follow all the steps of solving a physics problem, including setting up a coordinate system, labeling it with necessary variables, and solving the problem fully algebraically before substituting values. Do any necessary unit conversions using the chainlink conversion method. Make use of only the conversion relations 1 h = 60 min, 1 min = 60 s, and any other necessary conversion relations obtained from your knowledge of metric prefixes. Round your final answer to the correct number of significant figures
