You are moving due North on your tricycle with a velocity(0,20m/s). You aee a fellow tricyclist moving with relativevelocity 15m/s at an angle of 150 degrees. You have a mass of30 kg, the other has a mass of 40kg and both tricycles have a massof 10 kg. You collide and stick together
a) what is your velocity right after the collision?
b) Just after collision, at what angle are you moving withrespect to the x-axis
c) what is your speed after collision?
d) what is your change in KE from collision?
