Kinetic energy is the energy of motion. An
object that has motion - whether it is
vertical or horizontal motion - has kinetic
energy. It is expressed as:
KE = mV^2 /2
720 = 10.0v^2/2
V= 12 m/s

The event which happens at the end of the story of Thank You Ma'am is:
- <u>C. Roger leaves and never sees Mrs. Jones again.</u>
The novel is titled Thank You Ma'am and written by Langston Hughes details the interaction which a young thief has with a wealthy woman and how her response to finding out he was a thief was different to what was expected.
After Mrs Jones discovers that Roger steals from her, she does not report him to the police, rather she takes him to her house!
She treats him kindly and trusts him, which shows another side of Roger which is that he is a kind hearted person who would do good if he is properly taken care of.
However, the end of the story shows Mrs Jones telling Roger goodnight and in the end they never see each other again, but Roger has learnt a very valuable lesson.
Therefore, the correct answer is option C

The ball’s speed and direction at the lowest point of trajectory are; 3.1 m/s and swing to the same angle on the other side
<h3>What is the speed at the lowest point?</h3>
We will assume that all of the motion will transfer to Kinetic Energy at the lowest point. Now, the difference in height will be;
Δh = (130 – 130*cos °5) = 0.49 cm
The change in PE is;
ΔP.E = mgΔh
ΔP.E = 9.8m/s² × 0.75kg × 0.049 m
ΔP.E = 0.36015 J
Formula for kinetic energy is;
K.E = ¹/₂*m*v²
From conservation of energy;
K.E = P.E
Thus;
¹/₂* 0.075 * v² = 0.36015
v = √[(0.36015 * 2)/0.075]
v = 3.1 m/s
Thus, the pendulum will swing to the same angle on the other side.
