A 1500-\rm kg car drives at 30 \rm m/s around a flat circular track 300 \rm m in diameter. What are the magnitude and direction of the net force on the car? 9000N Since the net force is equivalent to the force of static friction, your answer to Part D is the magnitude f_s. Based on this value, what is the minimum coefficient mu_s of static friction between the road and the car?

A block slides from rest, along a track with an elevated left
end, a flat central part, into a relaxed spring, as shown in the
figure. The curved portion of the track is frictionless, as well as
the first portion of the flat part of L = 10 cm. The coefficient of
kinetic friction between the block and the only rough part, D = 10
