Sorry for the double post, but this edit wasnt showing up for me on other post, so i post it here.
I also came across another challenging problem, devising of an equation for Acceleration on an inclined plane.
Q: A toy car is released from rest at the top of a ramp going down to the right. Assuming that friction IS present derive an equation that could determine the acceleration of the car.
SFy - sum of forces in the y direction
SFx - sum of forces in the x direction
Fn - Force Natural
Fgy - Force Gravity in the Y-direction
Fgx - Force Gravity in the X direction
m - Mass
a - Acceleration
U - Coefficient of Friction
Fg - Force of Gracity
Ff - Force of Friction
Here is my work, though I think i went wrong with the sin and cos values
SFy = Fn - Fgy = 0
Fn = Fgy
Fn = cos(Theta)Fg
SFx = Fgx - Ff = ma
SFx = Fgx - FnU = ma
SFx = Fgx = ma + FnU
SFx = sin(Theta)Fg = ma +cos(Theta)Fg
SFx = sin(Theta)Fg / cos(Theta)Fg = ma + U
SFx = tan(Theta) = ma + U
SFx = tan(Theta) - U = ma
SFx = [tan(Theta) - U] / m = a
Once again help would be appreciated..thankz for all help and corrections
