NEED HELP ASAP! DUE NOW!! The formula for this type of energy is PE = mass x Height
A 1 kg rock is sitting at a height of 100 meters.
What is its potential energy?
PE = 1 x 100. PE = 100 Use the same formula to calculate the potential energy of the same rock at each of the following heights and put the answers in the chart.

Height (m) Potential Energy (J)

0
1
20
50
100

What is the type of the reaction below? bacl2 + h2so4 → 2 hci + baso4 double replacement synthesis single replacement decomposition

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
