Solution :-
(Vx) = velocity of the x-component
(Vy) = velocity of the y- component
conserving the momentum in x-direction we have
m×2 = (m + 2m)Vx
Vx = 0.667 m/s
conserving the momentum in y-direction we hav e
2m×1.8 = (m + 2m)Vy
Vy = 1.2 m/s
speed = sqrt(0.667^ + 1.2^2) = 1.372m/s
direction = tan^-1 ( 1.2 / 0.667) = 60.93°

A 1200-kg car is moving at 19 m/s due north. A 1500-kg car is moving at 18 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. Determine the speed and direction of the combined two-car wreck immediately after the collision. direction North of East
Puck A of mass 240-g is traveling due east with a speed, v_Ai=10
m/s, on a level, frictionless air table when it collides with puck
B of mass 160 g traveling at 40° south of west with a speed,
v_Bi=15 m/s, on the same table. (See the diagram below.) When the
pucks collide, they stick together via Velcro surfaces that line
the circular boundaries of both pucks. Find the magnitude and
direction of the momentum of the tandem of pucks...
