force gravity is not in the y direction
Fx is the force down the plank, and without friction, the object is accelerating, and fx=ma, which is not zero
Fy cannot generally be Fx
Your answer doesn't make sense.
a crate on a frictionaless plank inclined at angle theta with respect to the horizontal. Which of the follwing relationships is true? (assume that the x-axis is parallel to the surface of the incline)
a)Fy = Fg
b)Fx=0
c)Fy=Fx
d)none of the above
*my answer would be c but i need to make sure ASAP
thx
