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
A volleyball is spiked so that it has the initial velocity of 15 m/s focussed downward at an angle of 53° below the horizontal. What is the horizontal component of the ball's velocity when the opposing player fields ball?
