009 (part 2 of 3) 10.0 points

b) What is the kinetic energy of the second
bullet? Answer in units of J.

• PHYSICS -

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
