9) A 2.00 kg box is launched up an inclined plane of angle 30 degrees with respect to the horizontal. The length of the inclined plane is 14.0 m. The coefficient of kinetic friction between the block and the inclined plane is u= 0.40. With what speed should the block be launched so that it just makes the top of the inclined plane? Work this problem using conservation of Energy. Hint: Conservation of Energy says that Wne+ ME, = ME,...
