13. You're driving north on a road with a speed vo = 10m/s. You approach a curve in the road that is a quarter circle with radius of curvature R =60m, with the road headed west as you leave the quarter circle. You accelerate at a constant rate through this section of road, and as you leave the quarter circle, your speed is of = 12m/s. Uf = 12 - Vo = 10- R = 60 m (a) Find the magnitude of your tangential acceleration as you drive through the quarter circle. (b) Find the magnitude of your centripetal (radial) acceleration as you've just entered the quarter circle. (c) Find the magnitude of your total acceleration as you've just entered the quarter circle. (d) What is the direction of your total acceleration as you've just entered the quarter circle? A. north B. east C. west D. south E. northeast F. northwest G. southeast H. southwest (e) Find the magnitude of your centripetal (radial) acceleration as you just leave the quarter circle. (f ) Find the magnitude of your total acceleration as you just leave the quarter circle. (g) What is the direction of your total acceleration as you just leave the quarter circle? A. north B. east C. west D. south E. northeast F. northwest G. southeast H. southwest
