A child rides a carousel with a radius of5.1 that rotates with a constant speed of2.2 m/s. Calculate the magnitude of the centripetal acceleration of the child.

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
