Question
A metal ball is thrown vertically upwards from the top of a tower with an initial velocity of 20 metres per seconds. If the ball took a total of 6 seconds to reach ground level, determine the height of the tower.
Answers
0 = h + Vi t - 4.9 t^2
or
0 = h + 20*6 - 4.9 * 36
or
0 = h + 20*6 - 4.9 * 36
