Title: A puck with a mass m1 = 28.0 g moving at 1.00 m/s approaches a stationary puck Post by: ppk on Apr 4, 2012 A puck with a mass m1 = 28.0 g moving at 1.00 m/s approaches a stationary puck with a mass m2 = 102 g on an air table and they undergo a two-dimensional elastic collision. As a result of their interaction, the incident puck moves away with a speed v1 = 0.785 m/s and the other puck moves away with a speed v2 in a different direction. What is the angle between the velocities v1 and v2?
A) 45.0° B) 90.0° C) 85.0° D) 123° E) 165° Title: Re: A puck with a mass m1 = 28.0 g moving at 1.00 m/s approaches a stationary puck Post by: sci_expert on Apr 6, 2012 D
