Question1
An unmarked police car, travelling a constant 93, is passed by a speeder. Accurately 1.20 s after the speeder passes, the policeman steps on accelerator. If the police car's acceleration is 2.10, and 9.60 elapses after the police car is passed until it overtakes the speeder (assumed moving at constant speed), what was speeder's speed?
If the police car's acceleration is 1.80, and 7.60 elapses after the police car is passed until it overtakes the speeder (assumed moving at constant speed), what was speeder's speed?
Question2
