Question 1

A 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0.00 s, the block has a displacement of

a velocity of

and an acceleration of

The force constant (spring constant) of the spring is closest to
◦ 15 N/m.
◦ 12 N/m.
◦ 14 N/m.
◦ 11 N/m.
◦ 13 N/m.

Question 2

An object of mass m = 8.0 kg is attached to an ideal spring and allowed to hang in the earth's gravitational field. The spring stretches

before it reaches its equilibrium position. If it were now allowed to oscillate by this spring, what would be its frequency?
◦ 1.6 Hz
◦ 0.28 × 10-3 Hz
◦ 3.4 Hz
◦ 0.52 Hz
