A car accelerates from rest at 1 m/s for 20 s along a straight road. It then moves at a constant speed for half an hour. It then decelerates uniformly to a stop in 30 s. Find the total distance covered by the car. Amina throws the ball straight upward and after 1 second it reaches its maximum height then it does free fall motion which takes 2 seconds. Calculate the maximum height and the velocity of the ball when it reaches the same level on its way down. (take g =10m/s³).
