Question

A point on a rotating turntable 18.5 cm from the center accelerates from rest to a final speed of 0.690 m/s in 1.60 s. At t = 1.26 s, find the magnitude and direction of each of the following.

(a) the radial acceleration
_________m/s2

toward the center
awayfrom the center
in thedirection of the rotation
in adirection opposite to the rotation

(b) the tangential acceleration
____________m/s2

toward the center
away from the center
in the direction of the rotation
in a direction opposite to the rotation

(c) the total acceleration of the point
_____________ m/s2

Explanation / Answer

no. #a.

a = V/t = 0.690/1.6

a = 0.43125 m/s
