Answer
The magnitude of the average force on the wall from the ball during the collision is
$~~574~N$
Work Step by Step
In part (a), we found that the magnitude of the impulse on the wall from the ball is $~~2.18~kg~m/s$
We can find the magnitude of the average force on the wall from the ball during the collision:
$F~t = J$
$F = \frac{J}{t}$
$F = \frac{2.18~kg~m/s}{3.80\times 10^{-3}~s}$
$F = 574~N$
The magnitude of the average force on the wall from the ball during the collision is
$~~574~N$.
