Answer:
1.5 m/
directed towards the center of the circle.
Step-by-step 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.
