An ?=20.0 g object is held against the free end of a spring of constant ?=25.0 N/m that is compressed a distance ?=10.0 cm from its equilibrium length. Once released, the object slides ?1=1.15 m across the tabletop and eventually lands ?2 = 0.74 m from the edge of the table on the floor, as shown in the figure. Calculate the coefficient of friction ? between the table and the object. The sliding distance includes the compression of the spring, and the tabletop is ℎ =1.00 m above the floor level.

1) ? = ?
Mickey, a daredevil mouse of mass 0.0201 kg, is attempting to become the world's first "mouse cannonball." He is loaded into a spring‑powered gun pointing up at some angle and is shot into the air. The gun's spring has a force constant of 55.9 N/m and is initially compressed a distance of 0.131 m from its relaxed position.
If Mickey has a constant horizontal speed of 2.17 m/s while he is flying through the air, how high ℎh above his initial location in the gun does Mickey soar? Assume ? =9.81 m/s2.
2) h = ?
