Two rocks collide in outer space. Before the collision, one rock had mass 12 kg and velocity ‹ 4300, −3000, 2550 › m/s. The other rock had mass 5 kg and velocity ‹ −500, 1900, 3600 › m/s. A 1 kg chunk of the first rock breaks off and sticks to the second rock. After the collision the 11 kg rock has velocity ‹ 1550, 250, 2000 › m/s. After the collision, what is the velocity of the other rock, whose mass is now 6 kg?

Question

Two rocks collide in outer space. Before the collision, one rock had mass 12 kg and velocity ‹ 4300, −3000, 2550 › m/s. The other rock had mass 5 kg and velocity ‹ −500, 1900, 3600 › m/s. A 1 kg chunk of the first rock breaks off and sticks to the second rock. After the collision the 11 kg rock has velocity ‹ 1550, 250, 2000 › m/s. After the collision, what is the velocity of the other rock, whose mass is now 6 kg?

Expert Solution
Step 1

Given data:

Mass of one rock, m1=12 kg

Velocity, v1=4300, -3000, 2550m/s

Mass of other rock, m2=5 kg

Velocity, v2=-500, 1900, 3600m/s

Mass of rock, m3=11 kg

Velocity, v3=1550, 250, 2000m/s

Mass of rock, m4=6 kg
