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.

It can be noted that the passage suggested that English women of the time were not treated equally as men.
This is an incomplete question. Therefore, an overview will be given. It should be noted that in the olden days, men held power over women.
Women aren't treated as equal to men. Also, the roles of women were defined by men. Women supported their families and took care of their homes.

Probability distributions are used to represent data and their probabilities
The table entry is given as:
<u>Age of House Number of Houses</u>
1 15
2 20
3 25
4 30
Start by calculating the probability of selecting a house that has a certain age.
This is calculated as:
So, we have:
This means that the graph that represents the probability distribution must show that the probability of 1 is 0.17; 2 is 0.22; 3 is 0.28; 4 is 0.33.
