Consider the track shown in the figure. The section AB is one quadrant of a circle of radius 2.0 m and is frictionless. B to C is a horizontal span 3.6 m long with a coefficient of kinetic friction μk = 0.20. The section CD under the spring is frictionless. A block of mass 1.0 kg is released from rest at A. After sliding on the track, it compresses the spring by 0.35 m . (Figure 1) Part A Determine the velocity of the block at point B. Express your answer to two significant figures and include the appropriate units. Part B Determine the thermal energy produced as the block slides from B to C. Express your answer to two significant figures and include the appropriate units. Part C Determine the velocity of the block at point C. Express your answer to two significant figures and include the appropriate units. Part D Determine the stiffness constant kk for the spring. Express your answer to two significant figures and include the appropriate units.
