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

57600cm/s²

Step-by-step 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)`) =
`(v^(2) )/(r)`

where v= velocity = 720cm/s

r=9cm

r= radius

`a_(c)`= 720² ÷ 9

`a_(c)`=
`(720 * 720)/(9)`= 57600cm/s²
