The velocity of a plane as a function of time is given by $v = 0.5 t \hat{ı} - 2 \cos (t) \hat{ȷ}$ . If the plane started from a point $r equals 5.0$ at $t equals 0$ , what is it's position at $t equals 12 s$ ?

A dog running around a park has a velocity described by $v = (0.03 t^{2} - 2.5) \hat{ı} + (- 0.1 t + 2) \hat{ȷ}$ . What is the dog's displacement vector in unit-vector notation from $t equals 15 s$ to $t equals 30 s$ ?
