A 30-Kg Mass Sliding on a Frictionless Surface Has a Velocity

question 4

Multiple Choice

A 3.0-kg mass sliding on a frictionless surface has a velocity of 5.0 m/s east when it undergoes a one-dimensional inelastic collision with a 2.0-kg mass that has an initial velocity of 2.0 m/s west. After the collision the 3.0-kg mass has a velocity of 1.0 m/s east. How much kinetic energy does the two-mass system lose during the collision?

• A) 22 J
• B) 24 J
• C) 26 J
• D) 20 J
• E) 28 J
