A man hammers a nail into the wall with 10 N of force. The force applied to the nail by the hammer is 50 N of force. What can be deduced from this information?
A. The hammer has a mechanical advantage of 40 N, because it added amount of force to the force applied to it.
B. The hammer has a mechanical advantage of 5, because it was able to do five times the amount of work as the man.
C. The hammer has a mechanical advantage of 5, because it was able to apply five times the amount of force as the man.
D. The hammer has a mechanical advantage of 40 N, because it was able to add energy to the hammer-man system.
