7. (15 points) The function h(t)=-16r2 +80+130 gives the height in feet of an object above g after / seconds. (i) Find the instantaneous velocity function v(t). (ii) Find the instantaneous velocity of the object at time t = 2. (iii) Find the instantaneous acceleration function a(t). (iv) Find the instantaneous acceleration of the object at time t = 2. (v) Is the object going up or down at time t = 2? Explain your answer !!! (vi) Is the object speeding or slowing at time t = 2? Explain your answer !!! 7.
