Transcribed Image Text:2. Another absent-minded physics professor has left his notebook on top of his car. The
notebook has mass m = 1 kg. If the coefficient of static friction is u=0.7, and if he is
driving at a speed of v = 20 m/sec, then what is the tightest corner he can turn without
the notebook sliding off? (Give your answer as the radius of an equivalent circle.)
