Julie has a mass of 33 kg when standing on the 6 meter diving board. (She is 6 meters above the water.) Julie jumps off the diving board. What is her potential energy while standing on the board?
J
What is her kinetic energy just before she hits the water?
J
What is Julie’s speed just as she hits the water?
m/s

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.Right before it hits the ground, the initial potential energy and the final kinetic energy will equal each other due to conservation of energy. If we solve for initial potential, we can find final kinetic energy.Cars in roller coasters always move the fastest at the bottoms of hills. This is related to the first concept in that at the bottom of hills all of the potential energy has been converted to kinetic energy, which means more speed

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.
