If a 40 kg rock fell from a cliff and had a speed of 31.3 m/s when it hit the ground, what is it’s kinetic energy?

Kinetic energy = (1/2) (mass) (speed)²

It doesn't matter what direction the object is moving, what happened to set it in motion, or what route it's following.

Kinetic energy = (1/2) (40 kg) (31.3 m/s)²

Kinetic energy = (20 kg) (979.69 m²/s²)

Kinetic energy = (20 x 979.69) (kg-m²/s²)

Kinetic energy = 19,594 joules

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
