Question

A golf ball with a mass of 45.9g moving at a speed of 50.0 m/s?

Answer 1

The velocity of the ball 2 after impact is 52.21 m/s.

Step-by-step explanation:

The subject of this question is Physics, specifically related to the concept of velocity and mass. In order to find the velocity of ball 2 after the impact, we can use the principle of conservation of momentum. When the two balls collide, the total momentum before the collision is equal to the total momentum after the collision. Since the two balls have equal masses, the velocity of ball 2 after the impact can be calculated using the formula:

1. Initial momentum of ball 1 = Final momentum of ball 1 + Final momentum of ball 2
2. mass of ball 1 × initial velocity of ball 1 = mass of ball 1 × final velocity of ball 1 + mass of ball 2 × final velocity of ball 2
3. 45.9g × 50.0 m/s = 45.9g × 0.50 m/s + 45.9g × final velocity of ball 2
4. 2400 = 0.50 × 45.9g + 45.9g × final velocity of ball 2
5. final velocity of ball 2 = (2400 - 0.50 × 45.9g) / 45.9g
6. final velocity of ball 2 = 52.21 m/s
