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.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
