A pigeon takes off from where it was initially on the ground, near where home base is located at Regions Field (close to 1st Ave. South and 14th street in Birmingham), and the bird flies at what you can consider a constant speed of 18 m/s along a direct straight line to Birmingham International Airport, where he lands on the roof of one of the main terminals there. 5.E. How many seconds does it take the bird to make this trip

Answer:

1.84 seconds

Step-by-step explanation:

Given

initial velocity u = 0m/s

final velocity v = 18m/s

To get the time it takes the bird to make this trip, we will use the equation of motion

v = u+gt

g is the acceleration due to gravity = 9.81m/s²

t is the time

Substitute into the formula:


18 = 0+(9.81)t\\18 = 9.81t\\9.81t = 18\\t = (18)/(9.81)\\ t = 1.84secs

Hence it took the bird 1.84seconds to make this trip
