N=0.4 The block's, Q:Chapter 06, Problem 026 GO Question A 200g mass attached to a horizontal spring oscillates at a frequency of 2.0Hz . The coefficients of static and kinetic friction between the hockey puck and the metal ramp are s = 0.40 and k = 0.30, respectively. What speed does the puck have when it slides back to starting point? Explain. Applying law of conservation of mechanical energy between (b) and (c) in figure, Q:The system in the figure is in a stationary state in its original state.
