The time of motion of the ball from the vertical height is independent of the horizontal velocity.
Horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.
The time of motion of ball dropped from a vertical height is calculated as follows;
where;
- <em>h </em><em>is the vertical height</em>
- <em>t </em><em>is the </em><em>time </em><em>of motion</em>
- <em>g </em><em>is acceleration due to gravity</em>
- <em />
<em> is the initial </em><em>vertical velocity</em>
From the equation above, we can conclude that time of motion of the ball from the vertical height is independent of the horizontal velocity.
If there is variation in drop time, it could be as a result of applied force when the ball is dropped. This applied force influences the initial velocity which in turn alters the drop time.
Generally, horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.

The wording of the choices is really unclear. With two resistors in parallel,
here's the situation:
-- The voltage across each resistor is the same as the voltage across
the other one. If the parallel combination is connected to the battery,
then the voltage across each resistor is the full battery voltage.
-- The current through each resistor is (V) / (the resistance of that resistor).
That's the same current as would flow through that resistor if the other one
were not there.
-- As long as the battery or other power supply holds out, neither of these
quantities changes.
Can you match this situation to one of the choices listed ?
It looks to me as if choice 'C' is the one that's most likely
trying to say this.
Answer:
i think its A. hope this helps!
The momentum of a fast object compared to that of a slow object even if they both have the same mass, is their velocities.
Having same mass but different velocities results in different momentum.
Example: mass = 10kg
Velocity 1 = 50 Velocity 2 = 100
Momentum 1 = 10×50 = 500 Ns
Momentum 2 = 10×100 = 1000 Ns
Hope it helped!
