An object with mass m1 = 2 kg traveling east at v1i = 2.8 m/s strikes an object with mass m2 = 3 kg traveling at v2i = 2 m/s in a direction q = 118° counterclockwise from the east. After the collision, the first object rebounds at v1f = 2.8 m/s in a direction 270° counterclockwise from east. (i.e. it is heading south).

What is the velocity of the center of mass (cm) of this system before the collision?

a) vcmix = ?? m/s

b) vcmiy = ?? m/s

What is the velocity of the center of mass of this system after the collision?

c) vcmfx = ?? m/s

d) vcmfy = ?? m/s

In the center-of-mass frame of reference, what is the velocity of the 2 kg object before the collision?

e) v1ix(cm) = ?? m/s

f) v1iy(cm) = ?? m/s

In the same reference frame, what is its velocity after the collision?

g) v1fx(cm) = ?? m/s

h) v1fy(cm) = ?? m/s
