# Train With The Constant Acceleration

A train is moving along a straight line with constant acceleration $$a$$. A body standing in the train throws a ball forward with a speed of $$10\text{ m/s}$$ at an angle of $$60^\circ$$ to the horizontal. The body has to move forward by $$1.15\text{ m}$$ inside to catch the ball back at the initial height.Find the acceleration of train ( in $$\text{m/s}^2$$).

Details and Assumptions:
Take $$g =10 \text{ m/s}^2$$ and use the estimation $$\sqrt{3} =1.73$$.
