What is wrong with the diagram is : ( 4 )
- The spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.
<h3>Gravitational potential energy vs kinetic energy</h3>
The maximum gravitational potential energy is located at the highest peak which the roller coaster attains while as the roller coaster comes down from the peak the gravitational potential energy decreases while the kinetic energy increases.
The point at which the roller coaster should attain it maximum kinetic energy should be at the lowest point ( i.e far left side of the bottom ).
Hence we can conclude that error in the diagram is the spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.

Answer:
At the Launch point
Explanation:
We are told that after the explosion, one of the halves landed at the point Y, which is a distance of 2R to the right side of the launch point.
This means that the only way one half of the object would have gone double the original distance of R is if it's velocity was two times that of the initial velocity. Furthermore, the only way that will make sense is if the other half fell straight down. So In conclusion, if air resistance is neglected, the other half will land at the initial velocity point which is at launch point.
Answer:
The speed doubles.
Explanation:
The speed of a wave in a string is:
v = √(T / ρ)
where T is the tension and ρ is the linear density (mass per length).
If T is held constant, and ρ decreases by 1/4, then:
v = √(T / (ρ/4))
v = √(4T / ρ)
v = 2√(T / ρ)
The speed doubles.
