4.63 * 4.10 work "in" in x direction
-3.79 * 3.86 work "out" in y direction (braking)
2.16 * -2.45 work "out" in z direction
now just add the results (not a vector)
4.63 * 4.10 - 3.79 * 3.86 - 2.16 * 2.45
Joules (scalar but does have sign)
A constant force,
F = (4.63, −3.79, 2.16) N,
acts on an object of mass 17.7 kg, causing a displacement of that object by
r = (4.10, 3.86, −2.45) m.
What is the total work done by this force?
Im pretty sure the work equals -k(x-xo) but im not really sure what the values of r are supposed to be working here
