Question

A 60.0-g object connected to a spring with a force constant of 20.0 N/m oscillates with an amplitude of 5.00 cm on a frictionless, horizontal surface.

(a) Find the speed of the object when its position is 1.15 cm. (Let 0 cm be the position of equilibrium.) At this point the energy is partially stored as potential energy of the spring and partially as kinetic energy of the object. m/s

(b) Find the kinetic energy when its position is 3.50 cm. mJ

(c) Find the potential energy when its position is 3.50 cm. mJ
