In this sheetu will create sections labeled according to the heading 2 labels on the Canvas page you are creating - and then make subsections corresponding to the number of each question (1, 2, etc.). Use this sheet to make any calculations you need, taking care to write out each given value (and Its units) in its own row and then the calculated quantity (and units) in its own row. 2. In your individual Canvas group, create a page entitled "Force Needed". 3. Create a heading 2 "Law of the Lever\" and below ' questions: 1. 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 17.5 N at a distance of 0.600 m from the hinges, and the second child pushes at a distance of 0.450 m. What force must the second child exert to keep the door from moving? Assume friction is negligible. Include a diagram. 2. Two children of weight 200 N and 300 N sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 3.00 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? Include a diagram. 4. Create a Heading 2 "Mechanical Advantage", and below, in a numberedkiist, give and explain the answer to the following questions: 1. Suppose you needed to raise a 2,500 N lawnmower a distance of 0.060 cm above the ground to change a tire. If you had a 2.0 m long lever, where would you place the fulcrum if your force was limited to 300 N? Include a diagram. 2. Given the following simplied diagram for a car axle as a machine: Car axle simplied for mechanical advantage. Input force pulls along the central axis of the car with its moment arm equal to the axle radius. Output force pushes at the point where the tire meets the road with the moment arm equal to the tire radius. If a typical car has an axle with a radius of 0.0110 m and a tire with a radius of 0.275 m, what is its mechanical adva nta ge? . 'Il
