Impulse & Momentum Conservation

A football player is moving southward and suddenly turns eastward with the same speed to avoid an opponent. The force that acts on the player while turning is:

Show answer and solution

Answer: (b)

Force is along the change in momentum $\Delta\vec{p} = \vec{p}_f - \vec{p}_i$ .
$\vec{p}_f$ is east; $-\vec{p}_i$ is north (since $\vec{p}_i$ is south).
Equal east and north parts, so $\Delta\vec{p}$ points north-east.
So the answer is (b) along north-east.
