question 14

Multiple Choice

Explosions in one dimension: On a frictionless horizontal table, two blocks (A of mass 2.00 kg and B of mass 3.00 kg) are pressed together against an ideal massless spring that stores 75.0 J of elastic potential energy.

• D) 6.12 m/s (A), 5.00 m/s (B).
• E) 5.00 m/s (A), 6.12 m/s (B).
