A block of mass 2.40 kg is placed against a horizontal spring of constant k = 765 N/m and pushed so the spring compresses by 0.0500 m HINT (a) What is the elastic potential energy of the block spring system (in 3)? 0.96 when spring la compressed or stretched, the spring potential energy. , - x?, is always positive. Gravitational potential eners, Pomov, can be positive or negative depending on whether an object is above or below they reference height (b) of the block is now released and the surface is frictionless, calculate the block's speed (in m/s) after leaving the spring.
