## Question:

I attach a 2.0-kg block to a spring that obeys Hookes Lawand supply 16 J of energy to stretch the spring. I release the block; it oscillates with period 0.30s. The amplitude is

A) 38cm

B) 19cm

C) 9.5cm

D) 4.3cm

## Spring:

In a mass-spring system, the amplitude is the distance travelled by the mass after it is released from the sping. The energy stored in the spring due to the compression by an external force is expressed by the following equation:

$$E=\dfrac{1}{2}kx^{2}$$
