Question

I don't know how to conclude this exercise:

Answer 1

you have moving in xy plane to find trajectory u must know x(t) and y(t) and substitute t of x or t of y
to find x and y when u have equation of a u should integrate twice over time components of ax and ay

Answer 2

I don't understand what you typed ^^

Answer 3

You have motion in xy plane and you have to find tajectory
To do this you must know x(t) and y(t)

Answer 4

x(t)=1/2axt^2
y(t)=1/2ayt^2
trjectory is x(y)=ax/ay *y(t)

Answer 5

when you have a(t) and you wanna find x(t) you should integrate twice
