Here's the solution to question 3: Step 1: Identify the given values. The force required to get the block moving (static friction) is F_s = 26 N. The force required to keep the block moving at a constant velocity (kinetic friction) is F_k = 15 N. The static frictional coefficient is _s = 0.77. Step 2: Calculate the normal force (F_N). The formula for static friction is F_s = _s F_N. Rearrange to solve for F_N: F_N = (F_s)/(_s) Substitute the values: F_N = 26 N0.77 F_N ≈ 33.77 N Step 3: Calculate the kinetic frictional coefficient (_k). The formula for kinetic friction is F_k = _k F_N. Rearrange to solve for _k: _k = (F_k)/(F_N) Substitute the values: _k = 15 N33.77 N _k ≈ 0.44 The answers are: 3.1 Normal force exerted onto the block: 33.77 N 3.2 Kinetic frictional coefficient: 0.44 That's 2 down. 3 left today — send the next one.
