- Homework Statement
- Consider a block of mass 1 kg sitting on a plane inclined to an angle of theta = pi/6. Approximate the force due to gravity to be 10 N pointing straight down. Find the vector decomposition into tangent and perpendicular vector components by following the method above.

- Relevant Equations
- $$\vec v=\vec a+\vec b$$

$$\vec a = \vec g_{tangential}$$

$$\vec b = \vec g_{normal}$$

It's a puzzle. I have decomposed vector v by using formulas known from physics: m*g*sin(theta) and m*g*cos(theta).

I got: ##\vec v = (5, 5*\sqrt{3})##

But it has been marked as wrong. Consequently, the rest of my calculations is not correct. Could you tell me, why?
