A 2.00-kg object is attached to an ideal massless horizontal spring of spring constant 100.0 N/m and is at rest on a frictionless horizontal table.
 
  The spring is aligned along the x-axis and is fixed to a peg in the table. Suddenly this mass is struck by another 2.00-kg object traveling along the x-axis at 3.00 m/s, and the two masses stick together. What are the amplitude and period of the oscillations that result from this collision?
  A) 0.300 m, 1.26 s
  B) 0.300 m, 0.889 s
  C) 0.424 m, 0.889 s
  D) 0.424 m, 1.26 s
  E) 0.424 m, 5.00 s

Question 2

An object that weighs 2.450 N is attached to an ideal massless spring and undergoes simple harmonic oscillations with a period of 0.640 s. What is the spring constant of the spring?
 
  A) 2.45 N/m
  B) 12.1 N/m
  C) 24.1 N/m
  D) 0.102 N/m
  E) 0.610 N/m
