u=initial velocity
a=acceleration
s=displacement



time taken by the ball to reach the maximum height




At
height of ball is




i.e. ball is moving downward
height at 


To test a food for starch, you can add a few droplets of iodine to it, if the liquid changes to a blue/black color then starch is present. To test for sugar you can use Benedict's solution, which will also have a color change from blue to yellow/red/orange.
