A particle experiences a constant acceleration that is north at 100m/s^2. At t=0, its velocity vector is 70m/s east. At what time will the magnitude of the velocity be 100m/s?
____s

I will be happy to critique your thinking.
The east component will remain
Vx = 70 m/s
The west componen is
Vy = (1/2) a t^2 = 50 t^2
|V|= 100 when Vx^ + Vy^2 = 10^4 m^2/s^2
Write that equation in terms of t and solve for t.
Vx = 70 m/s
The west componen is
Vy = (1/2) a t^2 = 50 t^2
|V|= 100 when Vx^ + Vy^2 = 10^4 m^2/s^2
