It makes a collision with puck B, which has a mass of o.os6 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. +55 m/s 37 Before collision After Collision (a) Find the final speed of puck A. m/s (b) Find the final speed of puck B. m/s Submit Answer save Progress 2 clientasses docudoco

Explanation / Answer

applying momentum conservation for the collision,

0.036 x 5.5i + 0.056 x 0 = 0.036 vA (cos65i + sin65j) + 0.056 vB(cos37i - sin37j)

0.198i = (0.0152vA + 0.0447vB) i + (0.0326vA - 0.0337vB)j

along j direction,

0.0326 vA = 0.0337 vB

vA = 1.0337 vB

along i direction,

0.198 = 0.0152 vA + 0.0447vB

0.198 = 0.0152 (1.0337vB) + 0.0447 vB

vB = 3.28 m/s

vA = 3.39 m/s

(A) 3.39 m/s

(B) 3.28 m/s
