Quiz „General Engineering“

1 / 10

A racing car rolls to a stop on a horizontal course with an initial speed of v. It decelerates
only by friction with a rolling resistance of μF, which is supposed to be independent of
the current velocity.
What is the distance s the car needs to stop?
v = 300 km/h, μF = 0.15, g = 9.81 m/s2.
Give your answer in meters, rounded to four significant places.

Ekin = 0.5*m*v^2
W = Fr*s = μ*m*g*s
Kinetic energy of the car is completely converted by friction into heat and deformation work W. -> Ekin = W
s= v^2/2*μ*g
