I think it should be D. Because the potential energy of a roller coaster is at its lowest point or is the least at the bottom of the lowest point in the roller coaster. It is at its greatest at the top of the highest point of the roller coaster. Hope this helps! =^-^=

Answer: 6.67 x 10^-11 m^3•kg^-1•s^-2
Answer:
The kinetic energy of a 90 kg mass that is moving with a velocity of 6 m/s is 1620 J.
Explanation:
Given
To determine
The kinetic energy (K.E) of a body of mass of a 90 kg mass that is moving with a velocity of 6 m/s can be calculated using the formula
where
- K.E is the Kinetic energy (J)
substituting m = 90 and v = 6 in the formula
J
Therefore, the kinetic energy of a 90 kg mass that is moving with a velocity of 6 m/s is 1620 J.
Answer:
they can stop in less time rather than heavier cars or loaded trucks because of more mass and weight they tend to slow down in more time.
