A uniform board of length L=.75m is sliding along a smooth, frictionless horizontal plane. The board slides across a boundary with a rough horizontal surface. The coefficient of kinetic friection between the board and another second surface is μk= .31. The board has an initial speed of v=2.5m/s. How far past the boundary is the left end of the board when the board comes to rest? The answer was .654m, but I'm not getting any answer close to it, please help!

Can't get a good picture to post, but here's the link to one (just the picture not the questions):

An inclined plane is sliding, and accelerating, on a horizontal frictionless surface. There is a block at rest on the sloping surface, held in place by static friction through the horizontal acceleration of the system. The coefficient of static friction between the block and the inclined plane is 0.615. The slope of the incline plane is 40.5 degrees with respect to the horizontal. What is minimum acceleration of the inclined plane for the square block not to slide? What is...

A particle of mass m is constrained to lie along a frictionless, horizontal plane subject to a force given by F (x) = −kx + kx^3/A^2 where k and A are positive constants. The particle is projected from x = 0 to the right with initial kinetic energy T0. Find the turning points of the motion and the condition the total energy of the particle must satisfy if its motion is to exhibit turning points.

A mass sliding on a frictionless table is attached to a horizontal spring. It is noted to be at position x1 moving with a speed |v1|, and several seconds later at position x2 moving with a speed |v2|. What is the period of the mass attached to the spring? Choose x1 = 0.85m, x 2 = 1.1m, |v1| = 2.4m/s, and |v2|= 1.9m/s.
