A 32 kg child puts a 15 kg box into a 12 kg wagon. The child then pulls horizontally on the wagon with a force of 65 N. if the box does not move relative to the wagon, what is the static friction force on the box?

3 answers

Fap - Fs = 0,
65 - Fs = 0
Fs = 65 N. = Force of static friction.
fx=22cos35...18n
