Homework Statement[/B]A 2.0 kg ball moving with a speed of 3.0 m/s hits, elastically, an identical stationary ball as shown (The first ball is travelling to the right). If the first ball moves away with angle 30° to the original path, determine
- the speed of the first ball after the collision.
- the speed and direction of the second ball after the collision.
m1v1 + m2v2 = m1v1' + m2v2'
1/2 m1v1^2 + 1/2m2v2^2 = 1/2 m1v1'^2 + 1/2 m2v2'^2
The Attempt at a Solution
So far I understand that the conservation of momentum and energy can be used, however with the amount of different ways these formulas can be used I don't know where to go with them. Does anyone have any advice to help break this down algebraically?
