$(10$ points$)$ A $10\mathrm{.}0-kg$ object has the following acceleration vector:

vec$(a)=1\mathrm{.}20\frac{m}{s^2}$hat$(i)+2\mathrm{.}62\frac{m}{s^2}$hat$(j)$

$($a$)$ At this moment in time, what is the magnitude of the net force acting on the object?

$10\mathrm{.}0kg(9\mathrm{.}8101\mathrm{.}20i)(2\mathrm{.}62r\mathrm{.}81)$

$=1368\mathrm{.}54$

$($b$)$ Suppose this object started at
