Autumn uses a gift card to buy candy at a candy shop. The initial value of the gift card is $25. The function v = 25 – 2.50c represents the amount of money still left on the gift card v after purchasing c candy. Find the zero of this function. Describe what this value means in this context. *

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.
