An ice skater increases her speed from 10 m/s to 12.5 m/s over a period of 3 s while coming out of a curve of 20 m radius. What are the magnitudes of her radial, tangential, and total accelerations as she leaves the curve. (Remember that a r and a t are the vector components of total acceleration.) (a r = 7.81 m/s 2 , a t = 0.83 m/s 2 , a = 7.85 m/s 2 )
