Suppose that a particle's position is described by r(t)=(t+3)i+(t2+2)j. give an equation (in the form of a formula involving x and y set equal to 0 ) whose solutions consist of the path of the particle. find the velocity vector for the particle: v(t)

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
