7. A billiard ball is shot west at 2.30 m/s. A second, identical billiard ball is shot east at 1.30 m/s. The balls has a glancing collision, not a head-on-collision, deflecting the second ball by 90° and sending it south at 1.45 m/s. What is the speed of the first ball after the collision? m/s sf60 ssfo 160

**Physics Problem: Billiard Ball Collision**

A billiard ball is shot west at 2.30 m/s. A second, identical billiard ball is shot east at 1.30 m/s. The balls experience a glancing collision, not a head-on collision, which deflects the second ball by 90° and sends it south at 1.45 m/s. What is the speed of the first ball after the collision?

[Input Box] m/s

*Note*: The problem involves concepts of momentum and vector resolution in physics.

Expert Solution
Step 1

According to question---

given data-- 

  • Initial velocity of ball 1 = 2.30 m/s.
  • initial velocity of ball 2 = 1.30 m/s.
  • final velocity of ball 2 = 1.45 m/s.

We have to find-
