3. The same group of scientists mentioned in #1 wish to determine the coefficient of kinetic
friction for the same new material and asphalt. As they drag the object made of this new
material across asphalt at a constant speed of 5 m/s, the force sensor measures their pulling
force as 6 N. Determine the coefficient of kinetic friction for this new material and asphalt.
