PHYS 1301W Lecture 1: Characteristics of Friction

A car can decelerate at -5.00 m/s² withoutskidding whencoming to rest on a level road. What would be themagnitude of itsdeceleration if the road were inclined at12° uphill? Assume thesame staticfriction coefficient.

With its wheels locked, a van slides down a hill inclined at 36.0to the horizontal.

-Find the acceleration of this van if the hill is icy andfrictionless.

-Find the acceleration of this van if the coefficient of kineticfriction is 0.363.

A block is placed on a plane that is inclined at 60 degrees withrespect to the horizontal. If the block slides down the plane withan acceleration of g/2, determine the coefficient of kineticfriction between the block and the plane.
