How fast is the hummingbird flying around the bush?

What is the velocity of the hummingbird?

The velocity of the hummingbird is 720 cm/s.

What is the radius of the circular path?

The radius of the circular path is 9.0 cm.

What is the centripetal acceleration of the hummingbird?

Options:

A. 57,600 cm/s²

Answer:

The centripetal acceleration of the hummingbird is 57,600 cm/s².

The hummingbird flies in circles around a bush with a velocity of 720 cm/s and a radius of the circular path of 9.0 cm. The centripetal acceleration of the hummingbird is calculated using the formula:

Centripetal acceleration ([tex]a_{c}[/tex]) = [tex]\\frac{v^{2} }{r}[/tex]

where:

v = velocity = 720 cm/s

r = 9 cm

Plugging in the values, we get:

[tex]a_{c}[/tex] = 720² ÷ 9

[tex]a_{c}[/tex] = [tex]\\frac{720 * 720}{9}[/tex] = 57600 cm/s²

Therefore, the centripetal acceleration of the hummingbird is 57,600 cm/s².
