Solve the given question:
Question: An unsuspecting bird is coasting along in an easterly direction at 4.00 mph when a strong wind from the south imparts a constant acceleration of 0.400 m/s2.
Part A: If the acceleration from the wind lasts for 2.40 s, find the magnitude, r, and direction, θ, of the bird\'s displacement during this time period.
I need help to solve the above question and assume the bird is originally travelling in the x direction and there are 1609 m in 1 mile.
