A block of mass m = 2.00 kg is attached to a spring of force constant k = 480 N/m as shown in the figure below. The block is pulled to a position x, = 4.25 cm to the right of equilibrium and released from rest. k www m x= 0 x= x; (a) Find the speed the block has as it passes through equilibrium if the horizontal surface is frictionless. m/s (b) Find the speed the block has as it passes through equilibrium (for the first time) if the coefficient of friction between block and surface is HK = 0.350. m/s Need Help?

A block of mass 0.260 kg is placed on top of a light, vertical spring of force constant 4 875 N/m and pushed downward so that the spring is compressed by 0.095 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise?
