As the speed of the object increases, does the kinetic frictionincrease, decrease, or stay the same? Give a reason for your prediction.2. Derive an equation Start with Newton's 2nd Law and derive an equation for thekinetic frictional force in terms of the m, M, g, and a. Show all your work.FR= mg-(m+M)a3. Equipment Setup. Place the track on the table and put a block under each end.Slide the Motion Sensor onto the other end of the track. Attach the pulley to theend of the track at the edge of the table. The pulley height is adjustable. Connectthe AC adapter to the 850 interface. Connect the USB cord to the interface and aUSB port in the back of the laptop. Connect the cord of the Motion Sensor toPASPort1.4. Measure the Mass of the Block. Use the balance scale to get the mass of yourblock. Record in the data table.5. Get the type of material to be tested. The instructor will tell your group whichtype of surface to test.6. Setup the Block and Pulley. Place the larger area of the block on the track. Amass will be connected to the block by a string and that mass will be hung overthe pulley. Cut a length of string about 1.25 m long. Tie the string to the end ofthe block. Make a loop on the other end of the string for the mass.7. Open the file. In the Physics 231 Labs folder open the file Lab 7 KineticFriction. If the record button is grey, make sure the interface is connected to thelaptop correctly and has power.8. Setup the Hanging Mass. Get 100 g of mass and attach it to the end of thestring. Place the string over the pulley so the mass hangs down. Adjust the heightof the pulley so the string is horizontal over the track. Record the hanging massin the data table.9. Perform a Trial Run. Pull the block back until the mass is just belowStart the Motion Sensor. Release the block once you hear the sensor clicking.Make sure the sensor is finding the block all the way down the track (about 1.75– 2m away). The graphs for the position and velocity should be smooth. If not,adjust the sensor and try again.pulley.MacBook Pro

A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp. What problem could occur if the coefficient of friction were too high? pur answer: Packages would go too fast and could break at the end of the ramp. Packages could slow down too quickly and stop before the end of the ramp. Packages could break the ramp because gravity would increase. Packages could bounce off the ramp because normal force would increase. Clear answer

Answer Saved Suppose the roller skating woman has a mass of 41.3 kg. Her roller blades have a coefficient of kinetic friction 4g = 0.0306 with respect to the street. She approaches the car, slowing to a speed of v = 6.23 m/s when she touches the car. If the average force she exerts to slow herself down has a magnitude of F = 68.3 N how long does it take for her to come to a stop?
