In order to get a 15 kg object moving to the west a force of more than 25 Newtons must be exerted. Once it is moving however, a force of only 20 Newtons accelerates the object at 0.1 meters per second2 to the west. What is the force that static friction can exert on an object? What is the force of kinetic friction?
static force: 25 newtons to the east
kinetic force: 18.5 newtons to the east
