Question 7 This question relates to #15 on the Friction worksheet as shown below: 15. The chart above shows coefficients of friction between pairs of substances (like a steel cube on a steel bench for the first row). What two substances are likely to be involved if a 2.5 kg object made of one of these surfaces is on a horizontal surface made of the other substance and it takes a horizontal force of 13 N to make it start sliding? Choose the best answer to this question: What process would help you find the answer to #15? Your answer: O Find the coefficient of kinetic friction and compare it to the values on the chart. O Find the coefficient of static friction and compare it to the values on the chart. O Find the normal force and compare it to the values on the chart.
