A $2\mathrm{.}00-kg$ object undergoes an acceleration given by vec$(a)=(7\mathrm{.}00$hat$(i)+8\mathrm{.}00$hat$(j))\frac{m}{s^2}.$

$($a$)$ Find the resultant force acting on the object.

Work with $x$ and $y$ components separately.$+$

Review the definition of Newton's second law. hat$(j))$ N

$($b$)$ Find the magnitude of the resultant force.

$|vec(F)|=$

You appear to have correctly calculated the magnitude using your incorrect values from part $($a$).$ N
