The velocity of the ball at position A is 3.13 m/s.Since all energy is converted to KE.
<h3>What is potential energy?</h3>
The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.
A person has the most potential energy due to her position. when he is sitting on the highest point.
Given data;
Mass,m = .5 kg
Height,H = 0.5 m
Acceleration due to gravity,g = 9.8 m/s²
H is the height
The potential energy is found as;
The potential energy is mainly dependent upon the height of the object.
Potential energy = mgh
The potential energy at point B;
PE = mgh
PE = ( 1.5 kg) ( 9.8 m/s2) (0.5 m)
PE = 7.35 J
Since all energy is converted to KE, the kinetic energy at point B;
KE = 0.5mv^2
KE = PE
7.35 = 0.53(1.5) v^2
V = 3.13 m/s
Hence, the velocity of the ball at position A is 3.13 m/s.

Are you familiar with any basic calculus? If so, we can just look at this derivative and see what's happening with our units here..
Here it shows that acceleration is the derivative of velocity with respect to time. In other words, we can say that:
We can read that equation as: "acceleration is the change of velocity divided by the change in time (aka the time interval)."
If you're not familiar with calculus, we can use a simple equation of motion:
where:
vf = final velocity
vi = initial velocity
a = acceleration
t = observed time interval
We can rearrange this equation to find:
This is the same exact thing we wrote before!
C is the correct answer beacause it shows where it is happening in this cas “here”.

Explanation:
Tycho Brahe saw a super nova which inspired him to study astronomy.His observations are 5 times more accurate than other astronomers of his time and thus he was given a private island to study about astronomy .He made most accurate naked eye measurements ever.
So he can be said to be the "greatest naked eye astronomer of all time"
