you are moving due North on your tricycle with a velocity of (0,20m/s) You see a fellow tricyclist moving with relative velocity 15m/s at an angle of 150 degrees. You have a mass of 30 kg, the othertricyclist has a mass of 40 kg and the tricycles both have mass 10kg. You collide and stick together.
A) what is your velocity right after thecollision?
B) Just after the collision, at what angle are you moving withrespect to the x-axis?
C) What is your speed after the collision?
