A 6kg green ball with a speed of 2 m/s travels to the right and strikes a yellow ball of 3kg initially at rest. After the balls collide, the green ball continues to the right with a speed of 1 mls and the yellow ball moves to the right with a speed of 2 m/s Which of the statements is true?(adsbygoogle = window.adsbygoogle || []).push({});

1, The type of collision cannot be determined from the information given.

2. THe collision was totally inelastic.

3. The collision was inelastic.

I think it is 3 but I am not certain.

An open cart on a level surface is rolling without fricitonal loss through a vertical downpour of rain. As the cart rolls, rainwater accumulates in the cart. The mass will:

1. Decrease because of conservation of momentum.

2. Decrease because of conservation of mechanical energy.

3. Remain the same.

I think it is 1.

So you know - I am not cheating. I already did the quiz and got these questions wrong.
