A biock with mass m- 17 kg rests an a frictioniess table and is accclerated by a spring with spring constant k- 4249 N/m after being compressed a distance x, -0.556 m from the spring's unstretched length. The fioar is trictioniess cxcept for a rough patch a distance d- 2.3 m long. For this rough path, the cocfficient of friction is u. -0.45. 1) How much work is done by the spring as it accolerates the black? Suter 2) What s the speed of the block right after t leaves the spring m/sut How much work is done by friction as the block crosses the rough spot? Sutm 4) What s the speed of the block after it passes the rough spot? Suter 5) Instead, the spring is only compressed a distance x -0.157 m before being released. How far into the rough path does the block slide before coming tores?
