The motorcycle in the figure has a mass of m1 kg and its center of mass is at G1. The mass of the driver is m2 kg and the center of mass is at G2. Since there is μs between the wheels and the asphalt, determine whether it is possible for the driver to lift the front wheel off the ground. Neglect the mass of the wheels and assume that the front wheel can spin freely. a=0.41 m b= 0.39 m c= 0.75 m d= 0.25 m e=0.58 m m1=120 kg m2= 77 kg μs=0.82
