Energy problem formulas
Potential Energy = mgh
v = velocity or speed
Kinetic energy = mv²
9 = 9.8 m/s²
m = mass in kg
(Precision of 1)
h = height in meters
You serve a volleyball with a mass of 3.1 kg. The ball leaves your hand
with a speed of 20 m/s.
a) Calculate Kinetic Energy
(Precision of 1)
b) How much work is being done to the system to create this kinetic
energy?
