The coefficients of static andkinetic friction between the box and wall are 0.40 and0.30, respectively. The box slides down unless the appliedforce has magnitude 23 N. What is the mass of the box?
(II) On an icy day, you worry about parking your car in your driveway, which has an incline of 12°. Your neighbor’s driveway has an incline of 9.0°, and the driveway across the street is at 6.0°. The coefficient of static friction between tire rubber and ice is 0.15. Which driveway(s) will be safe to park in?
A child on a sled comes flying over the crest of a small hill,
as shown in Fig. 5–32. His sled does not leave the ground,
but he feels the normal force between his chest and the sled
decrease as he goes
over the hill. Explain
this decrease using
Newton's second law.
