Please help

2. A bird, starting from rest, accelerates at 3 m/s2 north for 5 seconds. It then sees the rest of its flock and turns due east accelerating from its previous speed to 20 m/s in 2 seconds.

A. What is the velocity of the bird after the initial leg (due north)?

B. How far does it fly during this first leg?

s = 1/2 at^2

v = at

2A.

v = 3*5 = 15m/s

2B.

s = 1/2 * 3 * 25 = 37.5m
