Question 7 (10 points)
Mazie stands on her kitchen floor. The coefficient of kinetic friction between her
socks and the floor is 0.62, and the coefficient of static friction is 0.75. She has a
mass of 42 kg.
a. If you push Mazie with a force of 350 N, will she start to slide? Explain your
answer. (2 points)
b. Mazie slides across the floor at a speed of 1.3m/s. What is the force of kinetic friction acting on her?
c. Mazie climbs up on the roof of her house, which has an angle of 35 degrees. The coefficient of static friction between her and the roof is 0.51. Will she slip off the roof? Explain your answer.
d. Given that the coefficient of static friction is 0.51 , what is the maximum angle the roof could have without her slipping?
