Also, please review one's class notes and textbook. 3) If the puck has a mass o Part a: \textbf {Part a:} Part a: The forces act on the puck are the normal and the gravitational which has the same magnitude but in the opposite direction, and the friction force which is in -ve direction. For a hockey puck on an icy surface, mK is relatively small, so the frictional force is similarly small. Synovial joints of the human. Frictional Force in Hockey: The Puck Stops Here Watch on Summary After learning about the concept of transfer of energy, specifically the loss of kinetic energy to friction, students get a chance to test friction. Refer to enricfemi's post. 0.1. . friction coefficient is greatly dependent on bearing type, bearing load, rotation speed and lubrication, etc. For example, friction slows a hockey puck. After traveling a distance of 75 m. The puck remains on the ice and slides 130 m before coming to rest. N Tries What is the coefficient of friction between the Physics-friction problem A 0.170 kg hockey puck is initially moving at 21.2 m/s [W] along the ice. A hockey puck on a frozen pond is given an initial speed of 20.0 m/s. physics. Student groups are each given a wooden block and different fabrics and weights and challenged to design the "best" puck. Learn about coefficient of friction topic of physics in details explained by subject experts on vedantu.com. The coefficient of static friction, typically denoted as μ s, is usually higher than the coefficient of kinetic friction. Assuming the coefficient of friction is about 0.1 for our puck on ice, using some basic kinematics and Newton's handy laws, that gives a stopping distance of just over 1000 m when the puck is hit with a starting speed of 160 km/hr. (F N) of 5 N Unknown Frictional force on the puck Equation m = I -Ff I / Fn Substitute 0.10 = I -Ff I / 5N . If the coefficient of kinetic friction between the ice and puck is 0.10, how far will the puck slide before stopping?
