Chapter 5, Problem 57GP
|| A 2 kg block is launched up a frictionless inclined plane by a spring as shown in Figure 5.64. The plane is inclined at 30° and the spring constant is 1000 N/m. The block is initially pushed against the spring in order to compress the spring 0.1 m, and then it is released. (a) Calculate the magnitude and direction of the acceleration of the block the moment after it is released. (b) Calculate the acceleration when the spring reaches the point where its compression is 0.05 m. (c) What are the magnitude and direction of the acceleration when the spring reaches the point where its compression is zero?
