Answer Each Question Appropriately $\frac { \mathrm { ds } } { \mathrm { dt } } = 9.8 \mathrm { t } - 5$

Answer each question appropriately.
-Suppose the velocity of a body moving along the s-axis is $\frac { \mathrm { ds } } { \mathrm { dt } } = 9.8 \mathrm { t } - 5$ .
Is it necessary to know the initial position of the body to find the body's displacement over some time interval? J your answer. ify

A) No, displacement has nothing to do with the position of the body.
B) Yes, knowing the initial position is the only way to find the exact positions at the beginning and end of the time interval. Those positions are needed to find the displacement.
C) No, the initial position is necessary to find the curve s= f(t) but not necessary to find the displacement. The initial position determines the integration constant. When finding the displacement the integration
Constant is subtracted out.
D) Yes, integration is not possible without knowing the initial position.
