Homework Equations
W=Fd
W=FdCos(angle)
The Attempt at a Solution
the first part worked out fine i had gotten
13982.004 J
but when I tired the second I got it wrong cause i did
W=FdCos(angle) and then subtracted it from the answer in the first part
and had gotten
-9618.56 J
and for the third part I just used
the equation
W=Fdcos(angle)
