A1.2 kg block is held at rest against the spring with a force constant k= 730 n/m. initially, the spring is compressed a distance d. when the block is released, it slides across a surface that is frictionless except for a rough patch of width 5.0 cm that has a coefficient of kinetic friction = 0.44. find d, such that the block's speed after crossing the rough patch is 2.3 m/s.

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
