Question

Chini is sliding blocks of different materials down a steel ramp. All of the blocks have similar sizes and masses. The table shows the coefficient of friction for several materials when sliding on steel. The larger the coefficient of friction, the greater the force of friction. In which order would the blocks reach the bottom of the ramp?

Material Coefficient of friction
aluminum 0.25
chromium 0.21
glass 0.12
steel 0.23
titanium 0.31

Answer 1

The blocks will reach the bottom of the ramp in ascending order of their coefficients of friction: glass, chromium, steel, aluminum, titanium.

Step-by-step explanation:

In order to determine the order in which the blocks will reach the bottom of the ramp, we need to consider their coefficients of friction. The larger the coefficient of friction, the greater the force of friction. Therefore, the blocks will reach the bottom of the ramp in ascending order of their coefficients of friction. Based on the table provided, the blocks would reach the bottom of the ramp in the following order: glass, chromium, steel, aluminum, titanium.
