Answer:
1.65 m
Explanation:
The motion of the ball is a projectile motion, so it is a parabolic motion with two independent motions:
- on the x-axis, a uniform motion with constant speed 
- on the y-axis, a uniformly accelerated motion with constant acceleration
downward.
First of all, we need to find the time t at which the ball has travelled halfway to the chatcher, i.e. at a distance of
. This can be found by using the relationship between distance, time and velocity along the horizontal direction:

So now we can move to the vertical motion, and we can calculate the distance covered vertically by the ball while falling for t=0.58 s, by using:

Assume that this is a direct current circuit.
V = IR
220 = I(1k)
I = .22 A
A scientific theory is something that can not be proven through experimentation, hope this helps
