Three blocks rest on a frictionless, horizontal table (see figure below), with m

Question

Three blocks rest on a frictionless, horizontal table (see figure below), with m1 = 9 kg and m3 = 16 kg. A horizontal force F = 104 N is applied to block 1, and the acceleration of all three blocks is found to be 3.2 m/s2.

A hockey puck slides along a rough, icy surface. It has an initial velocity of 32 m/s and slides to a stop after traveling a distance of 82 m. Find the coefficient of kinetic friction between the puck and the ice.

Explanation / Answer

A hockey puck slides along a rough, icy surface. It has an initial velocity of 32 m/s and slides to a stop after traveling a distance of 82 m. Find the coefficient of kinetic friction between the puck and the ice. Given that v = 32 m/s d = 82 m The workdone by frictional force is fk * d = 0.5 m v^2 ==> uk * m * g * d = 0.5 * m * v^2 ==> uk = [ v^2 /2* g * d ] = [ 32 * 32 / 2 * 9.8 * 82] = 0.6371
