Question

A blue and a green billiard ball, each with a mass of 0.15 kg, collide directly. Before the collision, the blue ball had a speed of 3 m/s while the green ball had a speed of 2 m/s. After the collision, the green ball stays in place while the blue ball continues in motion.

In 3-4 sentences, represent the situation before and after the collision and calculate the speed of the blue ball after the collision.

Answer 1

Legend has it... Jack is still waiting for an answer 1 year and 2 days later... (keep this going lol)

Answer 2

Just wondering how to find speed after collision of blue ball. I’m confused

Answer 3

Still waiting after 1 year, 4 months, 16 days

Answer 4

It has almost been 2 years and Jack is still waiting

Answer 5

Who knows how long its been anymore, but some still say that Jack is waiting all this time for an answer he is yet to receive

Before the collision, the blue ball has a mass of 0.15 kg and a speed of 3 m/s, while the green ball has a mass of 0.15 kg and a speed of 2 m/s. After the collision, the green ball comes to a stop and the blue ball continues in motion. To calculate the speed of the blue ball after the collision, we can use the principle of conservation of momentum. Momentum is the product of mass and velocity, and since momentum is conserved in a collision, we can set up an equation: (mass of blue ball) * (initial velocity of blue ball) = (mass of blue ball) * (final velocity of blue ball). Solving for the final velocity, we find that the speed of the blue ball after the collision is 4 m/s.
