Homework Statement
A pitcher can throw a baseball at 44 m/s. what is the ratio of kinetic energy to the rest energy E=mc^2. (can you use k=1/2mv^2 ?)
Homework Equations
rest energy=mc^2
K=gamma*mc^2 - mc^2
k=1/2mv^2
The Attempt at a Solution
I am just not sure how to go about this problem. It seems i can use k=1/2mv^2 because the velocity is well below c. From there i would take me kinetic energy and divide it by the rest enregy to get the ratio..??
