A 1.72-kg block, which starts with an initial speed of 0.326 m/s at the top of a ramp, slides down the ramp, which is inclined at an angle of 31.3° above the horizontal. The top of the ramp is 0.781 m higher than the bottom of the ramp. The block reaches the bottom of the ramp with a speed of 1.23 m/s. The block then slides along a horizontal smooth surface and collides with a spring with spring constant k=174 N/m. (a) Find the coefficient of kinetic friction between the block and the ramp. (b) Find the maximum distanced that the block compresses the spring before coming to rest.
