I love the way of speaking with youuu about this game but eh ni hun
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.

Free pts?? Is there a question??
There are different kinds of audio instrument. The speaker in the audio was en una tienda de ropa.
<h3>What are sound instruments?</h3>
All musical instruments are known to bring about sound. This makes matter to vibrate. The vibrations are known to bring about sound waves moving through the air.
A lot of musical instruments often uses resonance to make or increase the sound waves and make the sounds too be more louder. The voice in the audio is said to be that of en una tienda de ropa
