Homework Statement
A point on a rotating turntable 20.0 cm from the center accelerates from rest to a final
speed of .700m/s in 1.75s. At t=1.25s, find the magnitude and direction of (a) the radial
acceleration, (b) the tangential acceleration, and (c) the total acceleration at that point
Homework Equations
The Attempt at a Solution
I get the speed by comparing the the speed at 1.75s to speed at 1.25. I get
this to be .5m/s
To find the radial acceleration at that point I do (.5m/s)2/.20m = 1.25m/s2
Is the tangential acceleration at that point 1.25/1.25? Which is the radial/time?
