A single axis personal transport device starts from rest with the rider leaning slightly forward. Together, the two wheels weigh 25 lbs, and each has a radius of 10 in. The mass moment of inertia of the wheels
about the axle is 0.15 slug ft2. The combined weight of the rest of the device and the rider (excluding the wheels) is 200 lbs, and the center of gravity G of this weight is located at x = 4 in. in front of the
axle A and y = 36 in. above the ground. An initial clockwise torque M is applied by the motor to the wheels. The coefficients of static and kinetic friction are 0.7 and 0.6, respectively.
