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
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
