Kinetic energy is an
expression of the fact that a moving object can do work on anything it hits; it
quantifies the amount of work the object could do as a result of its motion. It
can be calculated as:
KE
= mv^2 /2
We
calculate the problem as follows:
KE
= mv^2 /2
400
= m(20)^2 / 2

Answer: exercise doing something you like. for example if you like dancing incorporate dancing in your workouts so you will be more likely to do it regularly
Explanation:
List the known information:

Use the kinematic equation
.
Plug in the given values:

This would be 35.064 m/s downward, or 35 m/s downward with significant figures taken into account.
It is definitely temerature.
Hoped this helped. :)
