As shown in the figure, a 1.50-kg box is held at rest against a spring with a force constant k = 790 N/m that is compressed a distance d. When the box is released, it slides across a surface that is frictionless, except for a rough patch that has a coefficient of kinetic friction u, = 0.400 and is 6.00 cm in length. If the speed of the box is 1.50 m/s after sliding across the rough patch, determine the initial compression d of the spring. cm Equilibrium position v=0' rough patch wwwwwn 6.00 cm

Each spring has an equilibrium length of 50.0 cm. When the springs are in equilibrium, they line up vertically. Suppose that the cup containing the mass is pulled to x= 70.0 cm to the left of the vertical and then released. 0.5 m x30.7 ml F www 0.5 m Determine (a) the system's total mechanical energy: b) the speed of the stone at x = 0.
A 50.0-g object is placed against the free end of a spring (k = 24.5 N/m) that is compressed 21.0 cm. Once released, LO000 the object slides a distance di = 1.55 m across the tabletop and eventually lands dz = 2.10 m from the edge of the table on the floor, as shown in the figure. The sliding distance on the tabletop includes the 21.0-cm compression of the spring, and the tabletop is h 1.00 m above the floor level. h Determine whether or not there is friction between the object and the table. If there is, determine the value of the kinetic friction coefficient . If there is not, enter 0.
