The combination of an applied force and a friction force produces a constant total torque of 35.9 N · m on a wheel rotating about a fixed axis. The applied force acts for 6.10 s. During this time, the angular speed of the wheel increases from 0 to 9.6 rad/s. The applied force is then removed, and the wheel comes to rest in 60.9 s. (a) Find the moment of inertia of the wheel. kg · m^2? (b) Find the...

(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...
