Aboy tries to walk forward, but the wind is so strong it pushes him backwards. which way is the net force vector pointing?

Backward

Explanation:

The motion will take place in the direction of the net force.

In this scenario there is a forward push and a backward push.

net force Forward push - backward push

is the backward push is greater than the forward push, then the net force will be negative i.e, directed backward

since the person is moving backward, the netforce is pointing in backward direction
