A stone is thrown directly upwards with an initial speed of 34.5 m/s . What is the maximum height the stone will reach?

2 answers

Maximum height is reached when all of the inital kinetic energy is converted to gravitational potential energy. This happens at height H given by
(1/2) M Vo^2 = M g H

H = Vo^2/(2g)

Vo is the initial velocity and g is the accleration of gravity.
