Question

Clyde and Marilyn are riding a roller coaster. During which section(s) of the track is their kinetic energy converted to potential energy?
A .from point B to point C only
B. from point A to point B only
C. from point A to point B and from point C to point D
d. from point B to point D only

Answer 1

Without a diagram we can't be sure what the answer is.

But in these sorts of situations, kinetic energy is converted into potential energy whenever the height of the rollercoaster increases (when it goes uphill). The higher you go, the more kinetic energy is converted into (gravitational) potential energy, until you've reached a maximum height where the all the kinetic energy is converted to potential energy and so the speed is 0 m/s.

Answer 2

U know
Kinetic energy=.5mv^2

Answer 3

Potential energy=mgh

Answer 4

Figure plz!!!!!!
