Motion question

2011 · Shift 2 · Q47

JEE AdvancedPhysicsMotionNumerical+4 / −1
A train is moving along a straight line with a constant acceleration 'a'. A boy standing in the train throws a ball forward with a speed of 10 m/s, at an angle of 60∘60^\circ60∘ to the horizontal. The boy has to move forward by 1.15 m inside the train to catch the ball back at the initial height. The acceleration of the train, in m/s2, is
