(time/2)^2 * a = H(think in terms of units, time is in s, accelleration is in M/s^2 therefore the result must be in metres)
(4/2) = 22^2 = 44*10 = 40 Metres high (taking gravity as 10M/s^2)
Code: [Select](4/2) = 22^2 = 44*10 = 40 Metres high (taking gravity as 10M/s^2)
the acceleration of it going up isn't the same as it coming down because you threw it.
