A 0.30 kg bird flies in a horizontal curve of radius 20 m at 15 m/s. The force exerted by the air on the bird is about Question 3 options:

a)

1.7 N

b)

3.48 N

c)

zero

d)

2.9 N

e)

4.5 N

Step-by-step explanation:

The bird will experience a centripetal force, this is the force exerted on a body that moves through a curve path.

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

The force is 3.37N

sine

step-by-step explanation:

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
