t(sec) 0 2 4 6 a(t) (f/sec) 5283 The data for the acceleration a(n) of a car from 0 to 6 seconds are given in the table above. If the velocity at 0 is 11 feet per second, the approximate value of the velocity at 6, computed using a left-hand Riemann sum with three subintervals of equal length, is 26 ft/sec (B) 30 ft/sec 37 ft/sec 39 ft/sec E 41 ft/sec
