A 0.40-kg cue ball makes a glancing blow to a stationary 0.30-kg billiard ball so that the cue ball deflects with a speed of 1.2 m/s at an angle of 30.0º from its original path. Calculate the original speed of the cue ball if the billiard ball ends up traveling at 1.5 m/s.
from its original path. Calculate the original speed of the cue ball if the billiard ball ends up traveling at 1.5 m/s.
I think i just use conservation of momentum here pt initial = pt Final? But the 30.0º from it's original path is throwing me off does it even come into it?
