Question

P1. The figure on the right represents part of the performance data of a car owned by a student. (a) Calculate from the graph the total distance traveled. (b) What distance does the car travel between the times t = 10 s and t = 40 s? (c) Draw a graph of its acceleration versus time between t = 0 and t = 50 s. (d) Write an equation for x as a function of time for each phase of the motion, represented by (i) 0a, (ii) ab, (iii) bc. (e) What is the average velocity of the car between t = 0 and t = 50 s?

P2. 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/s^2

to overtake 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
