When a bullet is fired upwards vertically it gains kinetic energy.
inertia
Gravity
In that case, the velocity is zero.
The time taken by the ball to reach the maximum height is 1 second. The maximum height reached by the ball is 36 meters.
It launches a a rocket vertically upwards with an initial speed of 40.0 m/s.

Vertical means straight up and down,aligned with the direction of gravity. Vertically upward means vertical in the up direction. So if you jump directly straight up that is vertically upward; when you land you are travelling vertically downward.
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!
Use the classic formula e = 1/2 x mv2
The time taken by the ball to reach the maximum height is 1 second. The maximum height reached by the ball is 36 meters.
it means initial upwards height times time in seconds
Using the equation: x=vot+(1/2)at2 x: -39.2m (though the object is thrown upwards, its total displacement is just the amount it fell from the tower). vo: initial velocity t: 4 s a: -9.8m/s2 (assuming we're on the earth's surface) -39.2=vo(4 s)+(1/2) (-9.8m/s2)(4 s)2 ((78.4 m - 39.2 m)/ 4 s) = v0 So the initial velocity is 9.8 m/s.
Earthquakes that causes most damage when two plates crashed and one plate moves upwards vertically than the other plate.
