When a particle is a distance r from the origin, its potential energy function is given by the equation U(r)=kr, where k is a co
nstant and r=x2+y2+z2−−−−−−−−−−√
(a) What are the SI units of k?
Part B (b) Find a mathematical expression in terms of x, y, and z for the y component of the force on the particle.
Part C (c) If U=3.00 J when the particle is 2.00 m from the origin, find the numerical value of the y component of the force on this particle when it is at the point (-1.00 m, 2.00 m, 3.00 m).

Answer:
Explanation:
Given:
- mass of solid cylinder,
- diameter of cylinder,
- mass of bucket of water,
<em>When the bucket is released to fall in the well, it fall under the acceleration due to gravity.</em>
We have formula for angular acceleration as:
where:
g = acceleration due to gravity
r = radius of the cylinder
