Two UFOs collide over Roswell, New Mexico. Before the collision, UFO A (mass 10,000.00kg) has a velocity of +100.00m/s and UFO B (mass 9000.00kg) had a velocity of -110.00m/s. When they collide they stick together. Please show how you did it.
a. What is the linear momentum vector of UFO A before the collision?
b. What is the linear momentum vector of UFO B before the collision?
c. What is the change in the velocity of UFO A due to the collision?
d. What is the change in the velocity of UFO B due to the collision?
e. Do these changes in velocities make sense? Why or why not?
