The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.022 kg and is moving along the x axis with a velocity of +5.5 m/s. It makes a collision with puck B, which has a mass of 0.062 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing.

If you finish the question I can answer it easily. What are the angles "shown in the drawing"? Are the final velocities what's wanted? Meanwhile I'll assume it's the same as the other puck question you posted.
GIVENS
masses m1, m2 = .022 .062
pre-collision velocities v1i, v2i = 5.5 0
post-collision angles Θ1f, Θ2f = 65 -37 deg
SETUP
P = m1v1i = .121
RESULTS
post-collision velocities v1f, v2f:
v1f = P / ((1/tan(Θ1f) - 1/tan(Θ2f))*m1*sin(Θ1f)) =
3.38392960822387 m/s
v2f = P / ((1/tan(Θ2f) - 1/tan(Θ1f))*m2*sin(Θ2f)) =
1.80827716609214 m/s

when I first began, i chanced on it complicated to be taught. i myself chanced on it much less complicated to shoot with a highway hockey %. for a protracted and severe distance (i might attempt to shoot it from my driveway onto my roof!) i understand that that's solid to apply genuine %., yet making use of a plastic highway hockey %. enables to strengthen the technique, then you definitely can upload power as quickly as you employ a black %.. right this is the thank you to do it (the wrist shot): a million. in the previous you stop and supply up you need to gain (like everybody else says) that it takes an invaluable style of prepare. notwithstanding it additionally takes an invaluable style of power. A airplane must be going an invaluable velocity in the previous it gets air, thats a similar with a %.. attempt getting your %. to a swifter velocity via bringing it forewords swifter. 2. start up the %. in the heel of your stick (like your foot, the tip is the toe, the section appropriate the place your stick starts off to curl is the heel.) in the back of your decrease back foot. Stand with your ft 2 ft aside. 3. Cup the %. with your stick as you carry it foreword (and it would be speedy) 4. only once you attain your front foot, open up the cup so as that the stick is not any longer cupping the %.. 5. proceed foreword on the un-cupped place until you sense like taking the stick off of the floor( approximately 2 inches in front of your front foot.). 6. A mili 2nd in the previous you're taking your stick off of the floor, notwithstanding, positioned the stick decrease back into its cupped place via rolling your wrists over. 7. which will spin the %.. and make it bypass swifter. thank you for analyzing. it may get very confusing, however the better section is to test. in case you do this in speedy action it would almost roll your wrists very speedy, as a result the wrist shot.
