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°

The Answer of 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°

A Puck with a Mass M1 = 28
