Adriver driving along a highway at a steady 45 mph (66 ft/sec) sees an accident ahead and slams on the brakes. what constant deceleration is required to stop the car in 242 ft? to find out, carry out the following steps. (1) solve the following initial value problem. startfraction d squared s over dt squared endfraction equals negative k (k constant), with startfraction ds over dt endfraction equals66 and sequals0 when tequals0 (2) find the value of t that makes startfraction ds over dt endfraction equals0. (the answer will involve k.) (3) find the value of k that makes sequals242 for the value of t found in the step (2).
