Homework Statement
Guys, consider the above image.
Let the incline to be smooth.
If I want to find NET WORK ..
There are 2 formulas ..
W = Fd and W = Change in Mecahnical Energy
In First Formula
Wnet = Wf + Wmg
Wnet = Fd - mgsin37 * d
In second Formula
Wnet = Change in KE + Change in PE
Fd = Change in KE + Change in PENot I got confused .. I know I am doing right..
But in first formula: Wnet = Wf + Wmg but in the second I substittued Fd only for Wnet
So which one is Wnet? I hope you get my point
Homework Equations
W = Fd
W = Change in KE + Change in PE
