LOL, that's not full solutions, that's just the equations which he should already know!

They are correct! You don't have to worry about us (static friction) in this problem though. Static friction is when the velocity and/or acceleration is not constant or mainly when you are trying to start an object, the us will be greater then uk. If the acceleration is constant there are forces...

Force of Gravity (Weight) and the Normal Force. if its just sitting at rest. The "Weight" would be due to the Earth and the "Normal" would be due to the table. along the y-axis they need to cancel out.

Also make your x,y axis as simple as possible. Try to put the axis along the most "kinematics" or "forces" what ever you working with. Its usually best to put a(y) "gravity" on the positive y axis.

Make sure to always draw a diagram and a fbd (free body diagram) it will always work! ;) v=v(o)+at x=x(0)+v(0)t+at^2 v^2=v(0)^2+2a(x-x(0)) x-x(0)=((v+v(0))/2)t *recall your constant accel equations? Then find your "y stuff" and then find your "x stuff" t (time) goes both ways! also remember...

READ IF YOU REALLY WANNA KNOW WHAT ITS LIKE TO BE A PHYSICIST! With a physics degree you can do a lot. I am being serious. The technology advancements of the present day are constantly increasing and the need for a well "trained" person who can think outside the box and do complicated...
