A ball thrown vertically upward returns to the starting point in 8 seconds.
-- Its velocity was upward for 4 seconds and downward for the other 4 seconds.
-- Its velocity was zero at the turning point, exactly 4 seconds after leaving the hand.
-- During the first 4 seconds, gravitational acceleration reduced the magnitude of its upward velocity by
(9.8 meters/second2) x (4 seconds) = 39.2 meters per second
-- So that had to be the magnitude of its initial upward velocity.
0 because initial is your starting point and the ball hasn't been thrown yet
initial velocity is the velocity with which a particle starts its journey.
The lighter the weight, the greater the initial velocity of shortening; inverse relationship.
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
As the starting length of the muscle is increased the initial velocity increases then decreases.
That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.

Initial velocity is the original starting velocity. I love math! It makes you smart like a math smart person.
the initial velocity of the rocket is zero.
Height reached = 3.7 metres.The mass of the ball is not really relevant.

A ball is thrown vertically upward from a point near the cornice of the tall building.It's just misses the cornice on the way down and passes a point of 160ft. below it's starting point . 5secs after declease the throwers hand. a.) what was the initial velocity of the ball? b.) How high did he tries about it's starting point c.)What was it's velocity on the highest point? d.)What was it's velocity as it pass the point 64ft. below the starting point e.) If the ball reach the ground in 7s how tall is the building ?
Well, (final velocity) = (initial velocity) + (acceleration x time)
