A. 20.0 ms SECTION B
A car travelling at a constant speed of 30ms' for 20s was suddenly
decelerated when the driver sighted a pot-hole. It took the driver 6s to get to
the pot-hole with a reduced speed of 18ms '. He maintained the speed for
another 10s to cross the pot-hole. The brakes were then applied and the car
came to rest 5s later. I. Draw the velocity-time graph for the journey.
II. Calculate the deceleration during the last 5s of the journey. III. Determine
the total distance covered.
