(Find time it takes a block to travel) Dynamics

[wildleaf]

Homework Statement

How long would it take for the block to travel 10m starting from zero velocity? (i.e. T =?)
(Look the the attached picture for the block and the position of it on the plane at 45 degree and 10 m from ground with the same slope)

Theta = 45 degrees
m = 1.0 kg
f = 0.3 (Friction Factor)
L = 10 m

Homework Equations

The Attempt at a Solution

I know we have to use the Newton's law and we have to assume that v = 0 @ T = 0. But I do not how to do it.

Draw a large diagram. Find the component of weight which acts perpendicularly to the slope. When you multiply this by 0.3 you have the friction force that acts along the slope.

That should get you started.

Is this what you mean (look at the attached picture).

You haven't drawn the triangle that resolves the weight into two components: one perpendicular to the slope, the other parallel to it.
