A 030-Kg Block of Wood Is Suspended on a Spring

question 12

Short Answer

A 0.30-kg block of wood is suspended on a spring. In equilibrium the wood stretches the
spring 2.0 cm downward. The wood is then pulled an additional distance of 1.0 cm down
and released from rest.
(a) How long does it take the wood to make 3 complete cycles of vibration?
(b) How much total mechanical energy does this system contain if we choose the total
potential energy (elastic and gravitational) to be zero at the equilibrium position of the
hanging block?
