2. a dog sits 1.5 m from the center of a merry-go-round. the merry-go-round is set in motion, and the dog's tangential speed is 1.5 m/s. what is the dog's centripetal
acceleration?

1.5 m/ directed towards the center of the circle.

Explanation:

Formula for Centripetal Acceleration

where v= represents the velocity of the object exhibiting circular motion and r represents the radius in which the body is doing a circular motion.

Given Parameters

v=1.5 m/s

r=1.5 m

Plugging in the values ,

= 1.5 m/ directed towards to the center of the circle.

v 154.9= 0.9 length length s little over 154.9cm
