Question

Two identical dragsters, starting from rest, accelerate side-by-side along a straight track. The wheels on one of the cars roll without slipping, while the wheels on the other slip during part of the time.
For which car, the winner or the loser, do the wheels roll without slipping?
a) Both dragsters reach the finish line at the same time.
b) the winner
c) the loser

Answer 1

It's impossible to say definitely. If static friction Us is greater than kinetic friction Uk (as it often is) AND the driver of the nonslipping car accelerates right at the edge of slipping, he wins. So possibly b). But possibly a) if Us = Uk and nonslip driver is at the edge, or c) if Us = Uk and slipping driver, when he is not slipping, is closer to the edge than nonslip driver.
