Transcribed Image Text:A man of mass M stands on a railroad car that is rounding an unbanked turn of radius R at speed v. His center
of mass is height L above the car, and his feet are distance d apart. The man is facing the direction of motion. How
much weight is on each of his feet?
Hints:
1) write the equation in vertical direction
2) sum of the torques with respect to center of
mass is zero
3) remember the radial equation of motion is
fi + f2 = M-
R
