A 72 kg person wearing skates with steel blades is on an ice rink. You will need to search for values in Table 5.1 to find the appropriate coefficients of friction to answer the following two questions.

What is the maximum static friction experienced by the person?

1 answer

To calculate the maximum static friction experienced by the person, we need to find the coefficient of static friction between steel blades and ice from Table 5.1. From the table, we see that the coefficient of static friction between steel blades and ice is typically around 0.02.

The formula to calculate maximum static friction is:

Maximum static friction = coefficient of static friction x normal force

The normal force acting on the person can be calculated using the formula:

Normal force = mass x acceleration due to gravity

Normal force = 72 kg x 9.8 m/s^2 = 705.6 N

Now, we can calculate the maximum static friction:

Maximum static friction = 0.02 x 705.6 N = 14.11 N

Therefore, the maximum static friction experienced by the person wearing skates with steel blades on ice is 14.11 N.
