A Disk of Mass M Moving in the Positive X

question 58

Multiple Choice

A disk of mass m moving in the positive x direction collides with a stationary disk,also of mass m.The first disk moves in a direction θ₁ with respect to the x axis,and the second disk moves off in a direction of θ₂ below the x axis,as shown in the figure.
If v = 10 m/s,θ₁ = 30°,and v_1f = 8 m/s,what is v_2f?

• A)6.9 m/s
• B)6.1 m/s
• C)2.0 m/s
• D)8.7 m/s
