ds Suppose that the velocity of a body moving along the s-axis is =v=9.8t-4. dt i) Find the body's displacement over the time interval t = 2 to t = 7 if s=3 when t = 0. ii) Find the body's displacement over the time interval t = 2 to t = 7 if s=-8 when t = 0. iii) Find the body's displacement over the time interval t = 2 to t=7 if s=So when t=0. i) The displacement over the time interval t = 2 to t = 7, given that s = 3 when t = 0, is (Simplify your answer. Type an integer or a decimal.) units.
