A motorist drives along a straight road at a constant speed of 15.0 m/s . Just as she passes a parked motorcycle police officer, the officer starts to accelerate at 2.00 m/s2 to over- take her. Assuming the officer maintains this acceleration, (a) determine the time it takes the police officer to reach the motorist. Find (b) the speed and (c) the total displacement of the officer as he overtakes the motorist.
You drive a beat-up pickup truck along a straight road for 8.4 km at 70 km/h, at which point the truck runs out of gasoline and stops. Over the next 30 min, you walk another 2.0 km farther along the road to a gasoline station. (a) What is your overall displacement from the beginning of your drive to your arrival at the station?
A commuter is driving a car along a straight road at a constant speed of 15.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 3.50 m/s2 to overtake her. Assume that the officer maintains this acceleration.
What If? Determine the answers to parts (a) through (c) of the problem, if instead of accelerating at the same instant the car passes him, the officer instead begins his acceleration 1.00 s after the car passes him. (Enter the time in s, speed in m/s, and displacement in m.)
