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.
