A object-spring system oscillates with an amplitude of 4.0 cm. If the spring constant is 210 N/m and object has a mass of 0.50 kg, determine each of the following values.
(a) the mechanical energy of the system

(b) the maximum speed of the object

(c) the maximum acceleration of the object

• Physics -

Calculate the angular frequency w. You should know the formula for that. If you don't, review your text.

Let A be the amplitude.

The energy in the sysyem is (1/2) k A^2
The maximum velocity is wA
The maximum acceleration in w^2 A
