An object moves along the y axis (marked in feet) so that its position at time x (in seconds) is given by the function f(z) = 110r - 1012. Find each of the following: (A) The instantaneous velocity v = f'(x). v = -20x + 110 (B) The velocity when z = 3 and z = 6 seconds (include units). Velocity at x = 3: 50 1 S Velocity at a = 6: -10 It (C) List all values of a when v = 0 (include units). Value(s) of I =
