The initial velocity is zero.
In most basic physics problems like this one the initial velocity will be zero
as a rule of thumb:
the initial velocity is always zero, unless otherwise stated, or this is what you are solving for
Cases where the initial velocity is not zero
examples
a cannon ball is shot out of a cannon at 50 mph
a ball is thrown from at a speed of 15 mph
etc
Acceleration = Final velocity - Initial velocity / time
This is a velocity question so u need to use uvaxt
Well, (final velocity) = (initial velocity) + (acceleration x time)
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
If the velocity is constant, thenDisplacement = (initial velocity) multiplied by (time)
The largest variation from two objects moving downward either 'dropped' or 'thrown' thereby allowing earth's natural gravity to increase until an object approaches and/or reaches maximum velocity. The difference in the two examples, 'dropped' or 'thrown' objects merely illustrates that the "thrown" object will reach maximum velocity quicker than the 'dropped' object.
If you simply release an object, the initial velocity is always zero.
The graph is a straight line through the origin, with a slope of (9.8 m/s) per second.
both the magnitudes and the directions of the initial and final velocities are the same.
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
Acceleration = Final velocity - Initial velocity / time
Because there's a constant downward vertical force on the ball, so it must accelerate downward. If you give it an initial upward velocity, the magnitude of that upward velocity must steadily decrease, and it must eventually dwindle to zero and then become downward velocity. The constant downward vertical force on the ball is the force of attraction between the mass of the ball and the mass of the Earth, caused by gravity.
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.

initial velocity is the velocity with which a particle starts its journey.
