1. A heavy crate (m = 23 kg) is resting on a frictionless inclined plane while suspended from a wall by a spring. The plane is inclined at an angle of 30° from the horizontal, and the spring is stretched from its equilibrium position by 25 cm. What is the spring constant of the spring? If the frictionless inclined plane is now replaced with an otherwise identical plane except with a rough surface, the crate now stretches the spring by 12 cm from its equilibrium position. What is the coefficient of static friction? You can assume that the static friction is at its maximum value. 30°

1. Consider the setup shown below: a block with mass m; sits on a table with friction coefficient u between the table and itself, attached on one side to a spring with stiffness k, and on the other side to a cord with negligible mass that wraps over a frictionless pully and supports a second block with mass m2 that's suspended in the air over the edge of the table. The friction between block 1 and the table is not enough to hold up block 2 so that, when it's released from rest, the spring stretches a distance Ax before the system comes to rest. a. Draw and label a free-body diagram for each block. (Use the gridlines to make sure that the relative lengths of your vector arrows are correct.) k m1 block 1: block 2: m2 b. What is the kinetic friction coefficient between block 1 and the table?

Current Attempt in Progress To measure the static friction coefficient between a 2.53-kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 467 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.0540 m, what is the coefficient of static friction? Number i eTextbook and Media Save for Later Units Attempts: 0 of 5 used Submit Answer
