A hockey player is moving northward and suddenly turns westward with the same speed to avoid an opponet. The force that acts on the player is.

A

Frictional force along westward

B

Muscle force along southward

C

Frictional force along south-west

D

Muscle force along south-west

Text Solution

Verified by Experts

The correct Answer is:
C
Consider the adjacent diagram

Let OA = `p_(1)` = initial momentum of player northward
`AB = p_(2)` = Final momentum of player towards west
Clearly `OB = OA + AB`
Change in momentum `=p_2 - p_1`
= Clearly resultant AR will be along south - west.
