The positions of a point (in feet) is given as a function of time t (in seconds). s = -17 + t - 14t²; t = 3 (a) Find the point's acceleration as a function of t. s"(t) = ft/sec² (b) Find the point's acceleration at the specified time. s"(3) = ft/sec² The positions of a point (in feet) is given as a function of time t (in seconds). s = √t + 4t²; t = 9 (a) Find the point's acceleration as a function of t. s"(t) = ft/sec² (b) Find the point's acceleration at the specified time. s"(9) = ft/sec² The positions of a point (in feet) is given as a function of time t (in seconds). s = -17 + t - 14t²; t = 3 (a) Find the point's acceleration as a function of t. s"(t) = ft/sec² (b) Find the point's acceleration at the specified time. s"(3) = ft/sec² The positions of a point (in feet) is given as a function of time t (in seconds). s = √t + 4t²; t = 9 (a) Find the point's acceleration as a function of t. s"(t) = ft/sec² (b) Find the point's acceleration at the specified time. s"(9) = ft/sec²
