A block of mass 3.0 kg is pressed against a spring (k = 3,100 N/m) near the bottom of a board inclined at = 28°, as shown in Figure A2.08. When released, the block is projected up the incline and the spring expands by 14 cm to its normal length. Using the law of conservation of energy, determine the maximum distance (d) traveled by the block up the incline, a. in the absence of friction. b. when the coefficient of kinetic friction between the block and the board is 0.20. Figure A2.08
