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 v₁_f = 8 m/s,what is v₂_f?

Question

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.

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 θ<sub>1</sub> with respect to the x axis,and the second disk moves off in a direction of θ<sub>2</sub> below the x axis,as shown in the figure. If v = 10 m/s,θ<sub>1</sub> = 30°,and v<sub>1</sub><sub>f</sub> = 8 m/s,what is v<sub>2</sub><sub>f</sub>? A) 6.9 m/s B) 6.1 m/s C) 2.0 m/s D) 8.7 m/s

If v = 10 m/s,θ₁ = 30°,and v₁_f = 8 m/s,what is v₂_f?
