Question
One billiard ball is shot east at 2.5 m/s. A second, identical billiard ball is shot west at 1.2 m/s. The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90∘ and sending it north at 1.46 m/s.
A.) What is the speed of the first ball after the collision? v=?
B.)What is the direction of the first ball after the collision? Give the direction as an angle south of east. Theta = ?
Transcribed Image Text:One billiard ball is shot east at 2.5 m/s. A second, identical billiard ball is
shot west at 1.2 m/s. The balls have a glancing collision, not a head-on
collision, deflecting the second ball by 90° and sending it north at 1.46
m/s.
