Homework Statement
The maximum power your body can deliver in lifting an object vertically is 78 W. How fast could you lift, at constant speed, a 2L full water container?
P=78W
m=2kg
t=?
v=?
Homework Equations
P=ΔE/t
E=1/2mv2
The Attempt at a Solution
78W=(.5*m*v2)/t
t=(.5*2*v2)/78
I am unsure what to do when I have a speed constant.
