2. kinetic energy and gravitational potential energy

key information:

ep = mass × graviational field strength × height

g = 10n/kg on earth.

a) the kingda ka rollercoaster has a maximum height of 139 m above the bottom of the ride. what would be the gravitational potential energy of a 60 kg student at the top of this ride?

b) the roller coaster then falls downwards to the bottom of the ride. how much gravitational potential energy will the student lose?

c) what has happened to this gravitational potential energy?

d) how much kinetic energy would the student have at the bottom of the ride?

e) what speed would the studenthave at the bottom of the ride?

answer: question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
