A stunt pilot performs a circular dive of radius 800 m. At the bottom of the dive (point B in the figure) the pilot has a speed of 200 m/s which at that instant is increasing at a rate of 20 m/s2. What acceleration does the pilot have at point B?
A)(50i + 20j) m/s2
B)(20i -50j) m/s2
C)(20i + 50j) m/s2
D)(-20i + 50j) m/s2
E)(-50i + 20j) m/s2
