question 73

Multiple Choice

At an instant when the distance between the two particles is 2.0 m, the kinetic energy of the moving particle is 16 J. Determine the distance separating the two particles when the moving particle is momentarily stopped.

• A) 0.75 m
• B) 0.84 m
• C) 0.95 m
• D) 0.68 m
• E) 0.56 m
