The net mass of the (shoed) basketball team is 392 kg. What is the maximum coefficient of the barefoot boys if they lose?

a) 0.351
b) 0.387
c) 0.425
d) 0.468

1. Without their shoes, members of a 9 person baseball team have a coefficient of static friction of only 0.23 . But the team wins a game of tug of war due to their superior mass of 638 kg. They are playing against a 5 person basketball team with a net mass of 415 kg. What is the maximum coefficient of static friction of the basketball team?

a) 0.321
b) 0.354
c) 0.389
d) 0.428
e) 0.471
