a car travelling at a constant speed of 30m/s for 20sec was suddenly decelerated when the driver sighted a pot hole. it took the driver 6s to get to the pot hole with reduced speed of 18m/s. he maintain the steady speed for another 10sec to cross the pot hole. the brakes were then applied and the car came to rest 5sec later. (a) draw the v-t graph for the journey (b) calculate decelaration during the last 5sec of the journey (c) calculate total distance covered

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
