Points: 0.25 of 1 The position of an object moving vertically along a line is given by the function s(t)=-4.912+32t+17. Find the velocity of the object over the following intervals. a. [0,4] b. [0,3] c. [0,2] d. [0.h], where h>0 is a real number a. The average velocity on the interval [0,4] is 12.4. (Simplify your answer.) b. The average velocity on the interval [0,3] is 17.3. (Simplify your answer.) c. The average velocity on the interval [0,2] is (Simplify your answer.)
