Two ice pucks (one orange and one blue) of equal mass are involved in a perfectly elastic glancing collision as shown in the figures below. The orange puck is initially moving to the right at   voi = 4.90 m/s, strikes the initially stationary blue puck, and moves off in a direction that makes an angle of ? = 37.0° with the horizontal axis while the blue puck makes an angle of ? = 53.0° with this axis as in the second figure. Note that for an elastic collision of two equal masses, the separation angle? + ? = 90.0°. Determine the speed of each puck after the collision in meters per second. v0f = ? m/s vbf = ? m/s

Question

Two ice pucks (one orange and one blue) of equal mass are involved in a perfectly elastic glancing collision as shown in the figures below. The orange puck is initially moving to the right at   voi = 4.90 m/s, strikes the initially stationary blue puck, and moves off in a direction that makes an angle of ? = 37.0° with the horizontal axis while the blue puck makes an angle of ? = 53.0° with this axis as in the second figure.

Note that for an elastic collision of two equal masses, the separation angle? + ? = 90.0°. Determine the speed of each puck after the collision in meters per second.

v0f = ? m/s

vbf = ? m/s
