A 2.0-kg block sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (k = 200 N/m) which has its other end fixed. If the block has a speed of 4.0 m/s as it passes through the equilibrium position, what is its speed when it is 20 cm from the equilibrium position?
 a. 2.6 m/s
  b. 3.1 m/s
  c. 3.5 m/s
  d. 1.9 m/s
  e. 2.3 m/s

Question 2

A spring (k = 200 N/m) is suspended with its upper end supported from a ceiling. With the spring hanging in its equilibrium configuration, an object (mass = 2.0 kg) is attached to the lower end and released from rest. What is the speed of the object after it has fallen 4.0 cm?
 a. 90 cm/s
  b. 79 cm/s
  c. 96 cm/s
  d. 83 cm/s
