A student wants to determine the coefficients of static frictionand kinetic friction between a box and a plank. She places the boxon the plank and gradually raises one end of the plank. When theangle of inclination with the horizontal reaches 30°, the box starts toslip, and it slides 2.4 m down the plankin 4.2 s at constant acceleration.
