PRACTICE ANOTHER
A student takes the elevator up to the fourth floor to see her favorite physics instructor. She stands on the floor of the elevator,
which is horizontal. Both the student and the elevator are solid objects, and they both accelerate upward at 5.05 m/s?. This
acceleration only occurs briefly at the beginning of the ride up. Her mass is 71.5 kg. What is the normal force exerted by the floor
of the elevator on the student during her brief acceleration? (Assume the f direction is upward.)
