Question

A hummingbird flies in circles around a bush. if the velocity of the hummingbird is 720 cm/s and the radius of the circular path is 9.0 cm, what is the centripetal acceleration of the hummingbird?

Answer 1

57,600 cm/s ^2 ...........

Answer 2

Answer:

57600cm/s²

Explanation:

centripetal accleration best describes the motion of the humming bird. it is the motion inwards towards the centre of a circle.

centripetal acceleration ($a_{c}$) = $\frac{v^{2} }{r}$

where v= velocity = 720cm/s

r=9cm

r= radius

$a_{c}$= 720² ÷ 9

$a_{c}$= $\frac{720 * 720}{9}$= 57600cm/s²
