Answer:
<h2>b) 3.48 N approx.</h2>
Step-by-step explanation:
<em>The bird will experience a centripetal force, this is the force exerted on a body that moves through a curve path.</em>

Fc=centripetal force
m=mass
v=velocity
r=radius
Step one:
given data
mass of bird m=0.3kg
the radius of curve r= 20m
velocity v= 15 m/s
Substituting we have

<u>The force is 3.37N</u>
