Two ice pucks (one orange and one blue) of equal mass are involved in a perfectly elastic glancing collision as shown in the figure below. The orange puck is initially moving to the right at voi = 6.5 m/s,strikes the initially stationary blue puck, and moves off in a direction that makes an angle of θ = 28° with the horizontal axis while the blue puck makes an angle of ϕ with this axis as in figure (b). Note that for an elastic collision of two equal masses, the separation angle θ + ϕ = 90.0°. Determine the speed of the orange puck after the collision.
