Problem

0.30\,\text{kg}

block is executing simple harmonic motion on a frictionless horizontal table with amplitude

0.12\,\text{m}

and time period

1.0\,\text{s}

. a. (i) Calculate its speed when it is

0.060\,\text{m}

away from the equilibrium position. b. (ii) Find the speed of the block at the instant when its potential energy equals its kinetic energy. c. (iii) If at

x=-0.060\,\text{m}

the block is moving toward the equilibrium position, state the sign of its velocity and justify your answer.
