detailed solution
Correct option is C
In figure, OA = p1 = initial momentum of player northward. OB = p2 = final momentum of player westward.According to trianglelaw of vectors,OA = AB = OBOA = OB = OA = p2- p1 = change in momentumThe change in momentum of player is along southwest.As motion is due to frictional force of reaction of the ground, therefore, force that acts on the player is frictional force along south west.Talk to our academic expert!
