Question

A dog chases a cat in a circular path around the base of a tree. the velocity of the dog is 5.4 m/s. if the centripetal acceleration of the dog is 48.6 m/s2, what is the radius of the path? 0.11 meters 0.60 meters 9.0 meters 17 meters

Answer 1

Its 0.6 pal, had the same question earlier and that's what i found. Hope it helps ;)

Answer 2

The correct answer is option B,
`0.6 m\\`

Step-by-step explanation:

Centripetal acceleration
`= (v^2)/(r)\\`

where "v" is the velocity of dog on the circular path

"r" is the radius of the circular path

Substituting the given values in above equation we get -

`a = (v^2)/(r) \\48.6 (m)/(s^2) = ( (5.4 (m)/(s))^2 )/(r)\\r = 0.6 m\\`
