1) You are driving a 4-wheel car and are stopped at a red light on the highway. When the light turns green, you accelerate at a constant rate until your speed is 40 m/s. a) If you were speeding up for 5.0 s, what was the angular acceleration of your wheels? Assume the wheels have radii of 0.30 m and aren't slipping on the road. b) Once your speed hits 40 m/s, you stop speeding up and drive at a constant speed. While moving at this speed, what is the total rotational kinetic energy of all four of your wheels? Assume each wheel has a mass of 9.1 kg and is a uniform solid disk (I =;mr²).

4. Consider again the situation given in Problem 1. (a) Find the center-of-mass of the system made up of m, and m,, taking the origin to be at P. (b) Draw a free body force diagram with the all of the mass (m, + m,) concentrated at this center-of-mass position. (c) Find the torque about P due to (m, + m2) concentrated at this center of mass position. How does this result compare to (d) in Problem 1? [We will make use of this technique often for certain types of future problems.]
