A police car waits in hiding slightly off the highway. A speeding car is spotted by the police car traveling at speed s = 32 m/s. At the instant the speeding car passes the police car, the police car accelerates forward from rest at a constant rate of a = 3.94 m/s2 to catch the speeding car. Assume the speeding car maintains its speed. a) Write an expression for the time it takes for the police car to catch the speeding car. Use the variables from the problem statement for your expression.  b) How long, in seconds, does it take for the police car to catch the speeding car?
