Momentum and Velocity After Collision

[rndomaccc]

A 3.50 kg ball with a velocity of 10.00 m/s collides with a stationary ball with a mass of 5.00 kg. After the collision, the first ball travels at a 42.6 degree angle from its original path, while the second ball travels at a -26.7 degree angle from the other ball's original path.

1) What is the momentum of each ball after the collision?

2) What is the velocity of each ball after the collision?

What work have you done so far?

i have p = 3.50kg x 10.00m/s = 35.00 Ns i have no idea what to do from here

How do you apply conservation of momentum?

How do you apply conservation of momentum?

do you use m₁v_1i+m₂v_2i=m₁v_1f+m₂v_2f?

[swansont]

do you use m₁v_1i+m₂v_2i=m₁v_1f+m₂v_2f?

 

 

 

Let's call the target object m₂. What is v_2i?

 

Also, momentum is a vector, so we can (and will need to) write this equation for both the x and y directions (let's say v_1i is in the x direction). What is v_1iy?
