Static friction, towards east

Vedclass · Answer

(B) When a person walks, they push the ground backward (towards the $West$) with their foot at the point of contact.According to Newton's $3^{rd}$ law of motion, the ground exerts an equal and opposite force on the person's foot in the forward direction (towards the $East$).Since the foot does not slip relative to the ground during the act of walking, the friction involved is static friction.Therefore, static friction acts on the person in the direction of motion, which is towards the $East$.Thus, the correct option is $B$.

$A$ person initially at rest starts walking towards the east without slipping or skidding. What is the type of friction acting on the person from the ground, and in which direction does the frictional force act?
