A 16.3-kg block rests on a horizontal table and is attached toone end of a massless, horizontal spring. By pulling horizontallyon the other end of the spring, someone causes the block toaccelerate uniformly and reach a speed of 5.99 m/s in 1.37 s. Inthe process, the spring is stretched by 0.180 m. The block is thenpulled at a constant speed of 5.99 m/s, during which timethe spring is stretched by only 0.0584 m. Find (a)the spring constant of the spring and (b) thecoefficient of kinetic friction between the block and thetable.
Can someone use these numbers, step by step with equations?
