Use the force diagrams below to write a net force equation of an object that is moving at a constant velocity. Then determine the magnitude of the missing force. 1. 2. F₁ = ? Fk=? Fr= 4.0 N 4.0 kg 3. Fr₁=2N FA= 7 N F₁₂=? II. Draw a force diagram, write net force equations, and determine the value of the missing force. 4. A 4.0 N box is slid across the floor at a constant velocity with a force of 2.0 N. Determine the magnitude of the frictional force between the box and the floor. 5. A 10.0 kg box is lifted upward with a constant velocity. Determine the magnitude of the force applied to lift the box. 6. A large toy rocket is fired straight up into the air at a constant velocity using rocket thrusters. The mass of the rocket is 20.0 kg. Determine the magnitude of the force from the thrusters. 7.
