Calculate the acceleration due to gravity, g.
A ball is thrown upward from the ground. It passes a window 10 m above the ground and is seen to descend past the window 2.2 s after it went by on its way up. It reaches the ground 3.6 s after it was thrown.Question asked by: tnel777

The acceleration due to gravity on earth is a constant and it is around 9.8m/s.
Therefore there is no need to actually do a calculation with figures as you already know if you are asked to calculate it and assuming you are on earth then this is the answer that you will get, a handy little shortcut for you ;)

Suppose,maximum height=h and accn. due to gravity=g.
or, h=0.605g ........(2)
Solving equations (1) and (2), we get the value of g = 9.85m/s^2
