1. [-/5.71 Points] DETAILS OSCOLPHYS1 9.2.003. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 175 N at a distance of 0.700 m from the hinges, and the second pushes at a distance of 0.400 m. What force must the second exert to keep the door from moving? Assume friction is negligible. Additional Materials 60 Reading 2. [-/5.71 Points] DETAILS OSCOLPHYS1 9.3.006. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Suppose a horse leans against a wall as in Figure 5.35. Calculate the force exerted on the wall assuming that force is horizontal and using the data in the schematic representation of the situation. Note that the force exerted on the wall is equal and opposite to the force exerted on the horse, keeping it in equilibrium. The total mass of the horse and rider is 750 kg. Take the data to be accurate to three digits. 130 14m 0.35 m () Figure 5.35 Additional Materials 20Reading
