Answer:
Kinetic energy = 135 kJ
Potential energy = 73.5 kJ
Explanation:
Mass of sky diver = 75 kg
Velocity = 60 m/s
Height = 100 m
Kinetic energy is given by the expression, 
, where m is the mass and v is the velocity.
So Kinetic energy = 
Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.
So, Potential energy = 75*9.8*100 = 73500J = 73.5 kJ
21 + 40? I didn’t really understand what you meant but hopefully this is what you’re looking for, these numbers add up to 61

Answer:
feet
Step-by-step explanation:
First, we need to find the height after one year:
2.25 + 1 1/6 = 
Now to find the amount in the second year, we can subtract the above amount from 5:
5 - =
So in the second year it grew feet

Step-by-step explanation:
We know that there are 2 pitcher of 64 ounces and 4 pitcher of 48 ounces.
To find the numerical expression, we must do:
(64×2)+(48×4)=Total amount of lemonade
128+192=320 ounces
So, Sandy has 320 ounces of lemonade.
