Two towers A and B. each of height 20 m are situated a distance 200 m apart. A body thrown horizontally from the top of the tower A with a velocity 20 ms−1 towards the tower B hits the ground at point P and another body thrown horizontally from the top of tower B with a velocity 30 ms−1 towards the tower A hits the ground at point Q. If a car starting from rest from P reaches Q in 10 seconds, the acceleration of the car is_______
(Acceleration due to gravity = 10 ms−2)
