Homework Statement
"A body whose mass is 2lb experiences an increase in velocity from 20 ft/s to 50 ft/s.
Determine the change in kinetic energy in BTUs"
Homework Equations
----
The Attempt at a Solution
As of right now I have [tex]\Delta[/tex]KE=2100 lb_m ft^2/s^2
I don't know how to change that into BTUs. I don't even know what BTUs are.
For example a joule is a kg*m/s^2, so what is a BTU in terms of pounds mass?
Thanks for any help
