A spring with spring constant of 250.0 N/m is suspended vertically with its upper end fixed to the ceiling and its lower end at position y=0.000 cm. A block of weight 25.0 N is attached to the lower end, held still for a moment and then released. What are the kinetic energy changes and the changes from initial values in the gravitational potential energy and elastic potential energy of the spring-block system when the block is at values of y equal to (a) -5.00 cm (b) -10.0 cm (c) -15.0 cm (d) -20.0 cm? Tabulate your results, include units at the top of each column.

An ?=20.0 gm=20.0 g object is held against the free end of a spring of constant ?=25.0 N/mk=25.0 N/m that is compressed a distance ?=10.0 cmx=10.0 cm from its equilibrium length. Once released, the object slides ?1=1.25 md1=1.25 m across the tabletop and eventually lands ?2=0.61 md2=0.61 m from the edge of the table on the floor, as shown in the figure. Calculate the coefficient of friction ?μ between the table and the object. The sliding distance includes the compression...

A spring with an unstrained length of 0.075 m and a spring constant of 2.2 N/m hangs vertically downward from the ceiling. A uniform electric field directed upward fills the region containing the spring. A sphere with a mass of 5.9 × 10-3 kg and a net charge of +7.2 μC is attached to the lower end of the spring. The spring is released slowly, until it reaches equilibrium. The equilibrium length of the spring is 0.063 m. What is...
