A device which tests the resistance to wear of two materials A and B is shown. If the link EO has a velocity of 3.8 ft/sec to the right when 8 = 46°, determine the magnitude of the rubbing velocity VA Assume a 4 in, b-11 in., r- 5 in.

One day, you are driving your car down the highway, and you notice that you are driving well over the speed limit. You apply the brakes of the carapplying a variable stopping force, until the car slows down to a rea sonable speed of 22.4 m/s (50 mph)A computer plots the force versus time for the vehicle and then measures the area under the curve. It is found that the area is - 18.950N . The total breaking time was 5.4 s. Given that the combined mass of you and your car 1sm = 1200 kg how fast were you moving before applying the breaks? What is the average force applied by the road to the car during breaking? (Note: 1Ns=1kg* m/s)

Im stuck on solving for f x-component

When defining a problem, you should divide the problem into three separate components. What are these components?
