Title: A curling stone slides on ice with a speed of 1.70 m/s and collides elastically Post by: ppk on Apr 4, 2012 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° Title: Re: A curling stone slides on ice with a speed of 1.70 m/s and collides elastically Post by: bio_man on Apr 6, 2012 A
