Mrs. buckley asked her physical science class to look at the graph and tell which of the following explanations are most likely true. option a: from 12 to 24 minutes the bicyclist was coasting down a hill. option b: at 35 minutes the bicyclist was not moving. option c: from 6 to 12 minutes the bicyclist was increasing his speed. option d: from 24 to 30 minutes the bicyclist was traveling down a steep hill. question 8 options: all of the options are most likely true. only option c is true. option a and b are true. option c and d are true.

I think it's D. Options C and D are true. The graph shows an increase in speed from points 6 to 12, which means Option C is true. It shows an even bigger increase in speed from points 24 to 30, and since bikes go faster when traveling downhill, I would think that Option D was correct as well.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
