Question
The drawing shows a collision between two pucks on an air-hockeytable. Puck A has a mass of 0.028 kgand is moving along the x axis with a velocity of +5.5m/s.It makes a collision with puck B, which has a mass of0.058 kg and is initially at rest. Thecollision is not head-on. After the collision, the two pucks flyapart withthe angles shown in the drawing.

(a) Find the final speed of puck A.
m/s

(b) Find the final speed of puck B.
m/s

Puck A mass = = 0.028kg; initial velocity and final velocity Puck B mass = ; initial velocity and final velocity the momentum of x components is conserved----------(1)The conservation of y- component momentssubstituting this in
