## Homework Statement

A block with mass m = 5.0 kg slides down an inclined plane of slope angle 36.5

^{o}with a constant velocity. It is then projected up the same plane with an initial speed 1.05 m/s. How far up the incline will the block move before coming to rest?

## The Attempt at a Solution

[tex] a_x = -g sin \theta [/tex]

[tex] \Delta v^2 = 2a \Delta x [/tex]

[tex] \frac{-v_o^2}{2a} = \Delta x [/tex]

[tex] \frac{-1.05^2}{-2gsin \theta} = \Delta x [/tex]

[tex] \frac{-1.05^2}{-11.658} = \Delta x [/tex]

But this wasn't right.
