A Curling Stone Slides on Ice with a Speed of 1.70

question 7

Multiple Choice

A curling stone slides on ice with a speed of 1.70 m/s and collides elastically with an identical, stationary curling stone. After the collision, the first stone has a velocity of 0.800 m/s in a direction that makes a counterclockwise angle of 61.9° with its original direction of travel. At what speed and what direction is the second stone traveling after the collision?

• A) 1.50 m/s at a clockwise angle of 28.1°
• B) 1.40 m/s at a clockwise angle of 19.1°
• C) 1.60 m/s at a clockwise angle of 34.2°
• D) 1.60 m/s at a clockwise angle of 28.1°
• E) 1.40 m/s at a clockwise angle of 32.3°
