A toy car rolls at a constant speed down a straight inclined track. When the car reaches the flat
surface at the base of the inclined track, the speed
of the car decreases.
Which statement best explains why the speed of
the car decreases when it reaches the flat surface?

Here is the answer!! :) I put it as a pic so you wouldn't plagiarize.

Explanation:

Hope this helps you!

seeing the graph would

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.
