A Mass of 0

question 105

Multiple Choice

A mass of 0.50 kg is attached to a massless spring with a spring constant k = 600 N/m see figure above) . The system rests on a level, friction-free surface and is initially at rest. A second mass of 0.20 kg makes an elastic head-on collision with the mass attached to the spring; thereafter, the oscillating system vibrates with an amplitude of 0.25 m. What was the incident speed of the second mass?

• A) 15 m/s
• B) 8.7 m/s
• C) 6.1 m/s
• D) 11 m/s
• E) 5.3 m/s
