A 45.0-g object connected to a spring with a force constant of50.0 N/m oscillates with an amplitude of 7.00 cm on a frictionless,horizontal surface.
(a) Find the total energy of the system.
(b) Find the speed of the object when its position is 1.30 cm. (Let0 cm be the position of equilibrium.)
(c) Find the kinetic energy when its position is 3.50 cm.
(d) Find the potential energy when its position is 3.50 cm.
