A 200-Kg Object Is Attached to an Ideal Massless Horizontal Spring

question 17

Multiple Choice

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
