2 1 point A meter stick is supported by a knife-edge at the 40.0 cm mark. Rolf hangs masses of m1 = 0.45 kg and m2 = 0.24 kg from the x1 = 13.9 cm and x2 = 52.0 cm marks, respectively. Find the point on the meter stick (in cm) Rolf must hang a third mass of m3 = 0.54 g to keep the stick balanced. Type your answer... 3 1 point A lemur pushes one side of a door with a force F1 = 39.2 NV a distance of x1 = 0.781 m from the hinges. A fossa pushes on the other side of the door a distance 2 = 0.577 m from the hinges. Both varmints apply their forces perpendicular to the surface of the door. What is the magnitude of the force (in ) the fossa applies to perfectly balance the lemur's torque? Type your answer... 4 1 point Masses are distributed in the x,y-plane as follows: . 5.41 kg at (-6.45, -2.27) m . 6.38 kg at (-0.60, 4.66) m . 6.79 kg at (3.63, 6.90) m What is the x-coordinate of the center of gravity of this system of masses? Type your answer... 6 1 point A lemur pushes one side of a door with a force F1 = 38.5 NV a distance of x1 = 0.704 m from the hinges A fossa pushes on the other side of the door with a force F2 = 20.1 N. Both varmints apply their forces perpendicular to the surface of the door. At what distance (in meters) from the hinges must the fossa apply the force to perfectly balance the lemur's torque?7 1 point A lemur pushes one side of a door with a force F1 = 30.4 NV a distance of x1 = 0.753 m from the hinges at an angle 01 = 74.10 with respect to the surface of the door. A fossa pushes on the other side of the door with a force F2 = 22.6 NVat an angle 0 = 79.10 with respect to the surface. At what distance (in meters) from the hinges must the fossa apply the force to perfectly balance the lemur's torque? Type your answer... 8 1 point A man opens a 1.49 m wide door by pushing on it with a force of 97.0 NV directed at an angle of 72.40 from the surface of the door. What is the magnitude torque (in N . m) he must applies about an axis through the hinges if the force is applied at the edge furthest from the hinges? Type your answer... 10 1 point A meter stick is supported by a knife-edge at the 50.0 cm mark. Rolf hangs masses of m1 = 0.24 kg and m2 = 0.52 kg from the x1 = 11.3 cm and x2 = 84.2 cm marks, respectively. Find the point on the meter stick (in cm) Rolf must hang a third mass of m3 = 0.67 kg to keep the stick balanced. Type your
