# A JEE - PROBLEM !

A train is moving along a straight line with a constant acceleration ' $$a$$ ' . A boy is standing in the train throws a ball forward with a speed of $$10 \text{ m s}^{-1}$$ , at an angle of $$60^{\circ}$$ 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. Find the value of the acceleration '$$a$$' in $$\text{ms}^{-2}$$?
