You are pushing horizontally on a couch with a force of 60N, but it's not moving. A) How much friction is present at that moment? You push hard until is start moving. After it is moving across the floor you are pushing it so it is going at a constant velocity of 0.25 m/s. B) If you pushing with a force of 140 N, how much friction force is there between the floor and the couch resisting the motion at...

An athlete is measuring the force by their flexor muscle by pulling a rope horizontally at a constant force. While pulling the rope the muscle applies a force on the forearm an angle of 71° as shown in the diagram. While keeping your forearm completely vertical, the tension in the rope is at 185N. The athlete's muscle is attached to the forearm 5 cm from the elbow joint and that the weight of your forearm is 22 N with a...
