Two bullets have masses of 3.4 g and 8.1 g,
respectively. Each is fired with a speed of 44.0
m/s.
a) What is the kinetic energy of the first
bullet? Answer in units of J.
009 (part 2 of 3) 10.0 points
b) What is the kinetic energy of the second
bullet? Answer in units of J.

You, or Billy, should know that the formula for kinetic energy (KE) is
KE = (1/2) M V^2.
To get the result in Joules, the mass M must be in kg and the velocity V im m/s.
Now do the numbers
