3. During a hockey game on a pond, the defenseman passes a 114-g hockey puck over the ice to the center, who fails to catch it. The puck is traveling at an initial speed of 6.7 m/s. It stops in 18 m due to the frictional force on it from the ice. a. Find the magnitude of the frictional force on the ice. b. What is the coefficient of kinetic friction between the puck and the ice?

3. During a hockey game on a pond, the defenseman passes a 114-g hockey puck over the ice to
the center, who fails to catch it. The puck is traveling at an initial speed of 6.7 m/s. It stops in
18 m due to the frictional force on it from the ice.
Find the magnitude of the frictional force on the ice.
a.
b. What is the coefficient of kinetic friction between the puck and the ice?
A sign with a mass of 1000.0 kg is suspended from a wall with a cable that is attached to th
at a point 3 m above a horizontal beam that causes the sign to be a distance of 4 m from
wall. See the diagram below. What is the tension in the cable? You may want to draw a
free-body diagram to help you solve the problem.
