Anna pushes horizontally on a 52-kg penguin with force of 10 N, but the penguin does not budge. Find the force of static friction between the penguin’s feet and the ground.

I have no idea where to start. Any help is appreciated. Thanks.

1. If the penguin isn't budging, the friction force equals the opposing force, 10 N.

This may be much less than the maximum static friction force possible, which is
52*g*mu(static).
