A box starts to slide down from a rough inclined plane at an initial height of h = 2.1 m as shown below. The box starts sliding from rest (the initial speed is zero) and reaches the bottom of the plane at a final speed of 3.3 m/s. The inclination angle is 0 = 11°. Find the friction coefficient p between the box and the plane by following the steps listed below. g V.=0 а IIIIIIII M h o Step 1. Find the distance traveled along the plane, L = Units Select an answer Step 2. Find the acceleration of the box, a = Units Select an answer Step 3. Finally find the friction coefficient, p = Units Select an answer
