Question 3 Suppose that the kinetic coefficient of friction between stone and grass is 0.7. A girl is sliding a stone cube (with mass = 8 kg) along the grass with a force of 72 N. What is the net force on the stone? Hint: This problem will require 3 steps! First, find the normal force that the grass is exerting on the stone by setting it equal to the gravitational force that the stone experiences. Next, use that force to calculate the force of kinetic friction as the stone slides. Last, can you find the net force that results from the push vs. the kinetic friction forces??
