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:
They land at the same time.
Explanation:
Two masses falling through a vacuum (no air resistance or buoyancy forces) will accelerate at the same rate when dropped from the same height. Therefore, despite having different masses, they land at the same time.
Hi there!
The energy that is about to or can be released from an object after energy has been transferred to it is called potential energy. In this case, as the diver jumps, potential energy is stored in the board as it bends. The potential energy is then released as kinetic energy when the board springs back up and the diver actually jumps.
Hope this helps!
Answer: Speed of galaxy B with respect to galaxy A = 0.8
Speed of galaxy C with respect to galaxy A = 1.4
Explanation:
Let the speed of galaxy A with respect to galaxy B be Vab & it is equal to Va - Vb = -0.8
Let the speed of galaxy C with respect to galaxy B be Vcb = Vc - Vb = 0.6
Speed of galaxy B with respect to galaxy A = Vba = Vb - Va = -Vab = -(-0.8) = 0.8
Speed of galaxy C with respect to galaxy A = Vca = Vc - Va
But from above, Vc - Vb = 0.6; Vc = 0.6 + Vb
And Va - Vb = -0.8; Va = -0.8 + Vb
Vca = Vc - Va = 0.6 + Vb - (-0.8 + Vb) = 0.6 + Vb + 0.8 - Vb = 0.6 + 0.8 = 1.4

Answer:
The force needed to keep the puck sliding at constant velocity is 0N
Explanation:
Since the ice friction and air resistance are neglected, the force needed to keep the puck sliding at constant velocity is 0N.
The acceleration due to gravity (g) will be zero since there is no ice friction and air resistance taken into consideration, and therefore,
F = m*g = m*0 = 0N
