Question:
A ball, mass m travels straight up, coming to a stop after it has risen a distance H
A) which equation Ef = Ei+W applies to the system of the *ball alone*?
A. 0 = 0.5*m*vi^2-mg
B. 0.5m*vi^2 = -mgh
C. 0+mgh = 0.5*m*vi^2+0
D. 0 = 0.5*m*vi^2+mgh
E. None of the above
B)
A. 0 = 0.5*mvi^2+mgh
B. 0 + mgh = 0.5*m*vi^2+0
C. 0.5*m*vi^2 = -mgh
D. 0 = 0.5*m*vi^2 - mgh
E. None of the above
