if a cart has 100 Joules of potential energy at the top and then 18 Joules of that gets converted into kinetic energy, how much potential energy does them cart still have?

If A Cart Has 100 Joules Of Potential Energy At The Top And Then 18 Joules Of That Gets Converted Into Kinetic Energy How Much Potential Energy Does Them Cart S class=

Sagot :

Answer:

82 J

Explanation:

The initial total energy was 100 J. Then, 18 J are converted to kinetic energy. By the conservation of energy, the total energy still will be 100 J, so the potential energy of the cart can be calculated as

PE + 18J = 100J

PE = 100J - 18J

PE = 82 J

Therefore, the cart still have 82J of potential energy.
