1 . Motion of an Object The position of an object moving along a straight line is given by s = t sqrt(4t2 + 2) (0 t 5) where s is measured in feet and t in seconds. Find the velocity v(t) and acceleration a(t) of the object after 2 sec. (Round your answers to three decimal places.) v(2)= ft/seca(2)= ft/sec2 2 . Find the derivative of the function. h(x) = 4 + x/(4x2 + 3)2 Find the derivative of the function. h(x) = (7 sqrtx+ 6)5
