Does a ball dropped with horizontal velocity take longer to hit the ground than on dropped at rest?

no because the ball is round and it would make no difference in what side you put it on because it has no sides

Will a ball thrown almost horizontally go the furthest?
No, this is an example of projectile motion. You should throw it at 45 degrees from the horizontal ground for it to have the maximum horizontal distance. This is because a sufficient height must be achieved, so that the ball can stay in the air longer and thus travel a longer distance while in flight.
What is the acceleration of an object that reache terminal velocity?
Zero, by definition. "Terminal velocity" implies that the velocity no longer changes.
What is the lowest velocity?
Lowest velocity round such as a 30.06 barrel has a longer barrel life.
Do objects dropped from greater distance hit with a greater force?
Yes. In the formula P=mv, momentum, which governs the force of the impact, is equal to the mass of the object multiplied by the velocity. As the velocity increases, so does the momentum, therefore the greater the height dropped from, the greater the force of impact.
What is terminal velocity and how to control it and why it occurs?
Terminal velocity is when air resistance balances out with gravity. For humans it's usually around 2000 ft of falling, gravity accelerates the person towards the ground at about 9.8m/s, as said person speeds up, air resistance increases and it becomes harder to accelerate. Terminal velocity is the point at which one may no longer accelerate. To control it: more air resistance = slower descent (terminal velocity comes sooner and is not as fast (i.e.parachutes), less air resistance = faster descent, it may take longer to reach terminal velocity as it is a much higher speed.
How does the angle of release affect the motion of a projectile both vertical and horizontal?
Smaller angles will result in a larger horizontal velocity and smaller vertical velocity. The times of flight will also be shorter since it's closer to the ground. Larger angles have a larger vertical velocity and smaller horizontal velocity. Time of flight will be much longer since it is higher above the ground. As for distance, 45 degrees will result in the greatest distance and for every distance before the furthest one there is an angle above 45 degrees and an angle below 45 degrees that will result in that distance.
Does a higher muzzle velocity equal a longer range?
All other factors equal (bullet mass & frontal area, angle of barrel, etc) a higher muzzle velocity will make the bullet travel further horizontally as if falls to the ground. If the barrel is level when fired , the bullet will hit the ground at the same time as a bullet dropped simutaneously from muzzle height

Does hang time depend on your vertical component of velocity when you jump?
The higher you jump the longer your hang time. Your height is dependant on the force applied to the ground at liftoff

Does it take longer for a raindrop to hit the ground if it is being blown horizontally by the wind than it would if it were falling perfectly vertical in a vacuum?
If both raindrops are dropped at the same time from the same height, then no, it does not take any longer, They will hit the ground at the same time because the vertical distance to the ground remains the same.One just travels further away
Do objects dropped from greater distance hit with a greater force?
Yes. In the formula P=mv, momentum, which governs the force of the impact, is equal to the mass of the object multiplied by the velocity. As the velocity increases, so does the momentum, therefore the greater the height dropped from, the greater the force of impact.
What will hit the ground first the bullet shot horizontally or the one dropped?
In theory, if a bullet dropped vertically at the same instant that a bullet is fired horizontally from a gun at the same height, they should both hit the ground at the same time.This example is used to emphasize that that horizontal motion and vertical motion may be analysed separately since they occur independently of each other.This is one of those things that works better in theory than in practice.There is a caveat that is important if you consider doing this in the real world. The process is not happening in a vacuum. The aerodynamics of the bullet fired at high speed is tremendously important. In early gun design, this was not understood and bullets fired from guns were very inaccurate and went up or down or right or left in unpredictable ways. Modern guns stabilize the trajectory by putting a spin on the bullet. The result makes the bullet act like a gyroscope and then to remain pointed forward when it encounters small anomalies in the air and wind. So, the moving bullet is subjected to vertical forces and can not be expected to drop at the same rate as a bullet with no horizontal motion.The principle of independent horizontal and vertical motion works better when illustrated by throwing and dropping heavy rocks. The principle is entirely correct, but there are more vertical forces involved than gravity with the bullets.
Can a person die from dropping a pillow from 40 thousand feet?
I'll assume that you mean having it dropped on him, and the answer is no. Terminal velocity is the speed at which a falling body no longer speeds up due to air resistance ... for a pillow that's slow.
What is better a longer or shorter arm on a trebucht?
A longer arm makes more velocity, longer distance, and more height
