Would it fall to the ground, the two horizontal forces cancelling each other out and the gravity remaining?

Excluding wind, it would just fall straight down.

Realistically, you would running at 100 mph would cause a gust of 100 mph wind to pull the ball after you a bit.

Well in your frame of reference it would move away from you at 100 miles per hour. In the frame of reference of someone watching you (someone who perceives you as moving at 100 mph), it would drop to the ground.

the point of release is static. the ball would fly in the forward direction at 100mph no matter how fast you are running backward.

Why don't they mount guns on the back of attack helicopters and other fast moving aircraft?

there's a japanese video where they do this with a car and the object pretty much drops straight down

>>6209668
because that's where the engines go, and if they're fast enough they don't need guns in the rear.

The ball travels at 100mph

Two possibilities:
You release the ball at 100 mph:
A) Relative to a non moving frame
B) Relative to your own frame

results:
A) the ball moves at 100 mph to the non moving frame, 200mph to you.
B) the balls moves at 0 mph to the non moving frame, 100 mph to you.

It would land on the point it was thrown from

the question clearly states you throw the ball at 100mph. mph is a measure of speed relative to a stationary point on earth (i.e it will travel 100 miles in an hour). You guys are speaking in terms of velocity (two objects speed relative to eachother) .

How can a ball travel 100 miles an hour or ever if it simply falls to the ground? Think about it.

> How can a ball travel 100 miles an hour or ever if it simply falls to the ground?
Because Galileo's ship.

The fact that there are people on /sci/ who don't even understand the basic idea of frames of reference is really fucking depressing.

>>6209747
Could you explain it to me please?

>>6209585
Depends if you throw the ball 100mph relative to yourself or relative to the ground.

Mythbusters did this by shooting a cannon from a moving truck. Sweet video:
