A spring with spring constant k = 125 N/m is used to pull a 25 N wooden block horizontally across a tabletop. The coefficient of friction between the block and the table is µ k = 0.20. By how much does this spring stretch from its equilibrium length?
Added by Kacia G.
Step 1
Given that the coefficient of friction is μk = 0.20 and the weight of the block is 25 N, the friction force can be calculated as: Friction force = μk * weight Friction force = 0.20 * 25 Friction force = 5 N Show more…

A block of mass m = 3.65 kg is placed on a table and attached to a spring with spring constant k = 150 N/m. The spring is pulled so that the block slides over the table at a constant speed of 0.50 m/s. If the coefficient of kinetic friction between the block and the table is ÎĽk = 0.3, how much is the spring extended beyond its equilibrium length? Give your answer in centimeters.

An object with mass (m) is placed against the free end of the spring. From equilibrium length, which is a distance of 1.25 from the edge of the tabletop and eventually lands a distance (d) from the table top. If d = 1.60 meters, h = 1.0 meters, m = 100 g, k = 75 N/m, and x = 0.15 m, calculate the coefficient of kinetic friction for the interaction between the block and the table.
