Help me please!
a)The impulse is:Originally Posted by pocahontas
$\displaystyle \int_0^T \ F(t)\ dt$,
$\displaystyle T$, the duration over which the force is acting, so in this case it is the shaded area in the figure.
b)The average force is:
$\displaystyle \frac{\left(\int_0^T\ F\ dt\right)}{T} $
so is the shaded area divided by 0.14s.
