5. Push the box and find the force needed to make the box to start moving. Add more mass (box, kid, man, refrigerator, basket as needed) and repeat the procedure such that you complete the table below. Hint: Weight = mass x gravity Magnitude of Normal Force = Magnitude of the Weight Weight (N) Mass Normal Force of (kg) Force (N) Static Friction (N) 50 90 130 150 180

Please rank the following objects by the magnitude of the normal force acting on them.  1.    A 80 g gecko crawling up the wall  2.    A 60 g caterpillar crawling up a 45 degrees incline  3.    A 35 g beetle crawling on the floor  Please rank correctly.

In the figure, is the tension in the rope between the ceiling and Superhero the same as the tension in the rope between Superhero and Trusty Sidekick? A. Jimmy: "Yes, of course it is the same. It's a single rope with a single tension force on both ends. Booyah!" B. Emmy: "I think they are different. The tension in the space between Superhero and Trusty Sidekick only has to hold up Trusty Sidekick, but the tension above Superhero has to hold up both Superhero and Trusty Sidekick. C. Timmy: "Wouldn't your, 'both ends' be the end on the ceiling and the end at Trusty Sidekick? How can you have a different 'both ends' for the space between Superhero and Trusty Sidekick? Wouldn't that only work if they had two different ropes? Or if the rope breaks? The rope clearly holds, so the tension force must be the same everywhere along the rope. " D Figure 438 Superhers and Tunty Sickick hang mess on a pe as they try to figure out what to do next Will the tension the the same everywhere in the p

4. You are pushing horizontally with a 300 N force on a box that is on an inclined plane as shown. The mass of the box is 30 kg and the incline is at a 25 degree angle off the Fapplied horizontal. The coefficient of kinetic friction between the box and the incline is 0.3, and the coefficient of static friction i 0.4. Assuming the box was at rest at t=0 when the force is initially applied, is the box moving up the ramp, down the ramp, or is it at rest after the force has been applied? 25⁰
