A curling stone slides on ice with a speed of 2.0 m/s and collides inelastically with an identical, stationary curling stone.
After the collision, the first stone is deflected by a counterclockwise angle of 28 from its original direction of travel, and the second stone moves in a direction that makes a 42 clockwise angle with the original direction of travel of the first stone. What fraction of the initial energy is lost in this collision? A) 0.12
B) 0.24
C) 0.36
D) 0.48
E) 0.64
Question 2

A) be a relative maximum.
B) be a relative minimum.
C) be neither a relative maximum nor a relative minimum.
D) oscillate between being a relative maximum and a relative minimum.
