A particle's position as a function of time

t

is given by

vec(r)=(5.0t+6.0t^(2))mhat(i)+(7.0-3.0t^(3))mhat(j)

.\ Part A\ At

t=5.0s

, find the magnitude of the particle's displacement vector

\\\\Delta vec(r)

relative to the point

vec(r)_(0)=(0.0hat(i)+7.0hat(j))m

. Express your answer using two significant figures.

r=(5.0t+6.0t2)mi^+(7.03.0t3)mj^ At t=5.0s, find the magnitude of the particle's displacement vector r relative to the point r0=(0.0i^+7.0j^)m. Express your answer using two significant figures
