(a) A car accelerates from rest at 1 mis for 20 s along a straight road. It then moves at a constant speed for haf anhour. It then decelerates unifomly to a stop in 30 s. Find the total distance covered by the car.(b) Amina throws the bal straight upward and ater 1 second k reaches is maximum heightthen it does free fall motion which takes 2 seconds. Calculate the maimum height and thevelodity of the ball when it reaches the same level on its way down (take g = 10 m's)
