Determine the magnitude of its acceleration when t = t 2 . How far has it traveled in t = t 2 ? Use Simpson s rule with n steps to evaluate the integral. Given: 100 ft = t 1 4s = b 60 ft s = c 1 s 2 = t 2 2s = n 50 = Solution: tt 2 = 1 e 2 = a t 2 bcte 2 = a n v 2 = t 2 a n 2 + = a 35.0 ft s 2 = s 2 0 t 2 t b 1 e 2 d = s 2 67.1 ft = Problem 12-135 A particle P travels along an elliptical spiral path such that its position vector
