Homework Statement
A body of mass m accelerates uniformly from rest to a speed [tex]v_{f}[/tex]
in time [tex]t_{f}[/tex]
Show that the work done on the body as a function of time, in terms of [tex]v_{f}[/tex],[tex]t_{f}[/tex] is:
[tex]\frac{1}{2}m\frac{v_{f}^2}{t_{f}^2} t^2[/tex]
Homework Equations
1)[tex] W=\int F*dx[/tex]
2)[tex]V_{f}=at[/tex]
3)[tex]F=m\frac{V}{t}[/tex]
The Attempt at a Solution
Well I know I would start out integrating equation 1 with equation 3.
Then what?
