1. A car is moving in a linear path with accelerates from rest at constant acceleration for a distance of 300 m. It then maintains the velocity for 15 seconds before the driver hits the brake after seeing a dog on the road. Given that the velocity v, during the braking is v = 30 cost, where t = 0 s when the braking is applied, (a) Find out the time taken for the car to come to a stop. (3 marks) (b) Find out the acceleration of the car during the first 300 m. (5 marks) (C) Find the total distance travelled by the car from rest to stop. (5 marks) (d) sketch the velocity-time (v-t) graph of the car from rest to stop. (4 marks)
