In a 300-rough incline, a 2.15 kg block is initially at rest beside a spring that is compressed by 42 cm as shown in the figure below. The spring has a spring constant of 180 N/m and the coefficient of sliding friction between the incline and the block is 0.32. When the spring is released, (a) how far up the incline (with respect to its initial position) will the block slide before sliding back? (b) What is the speed of the block at the instant it is 0.43 m from its initial position? 30°
