  Question

A brick of mass has been placed on a rubber cushion of mass . Together they are sliding to the right at constant velocity on an ice-covered parking lot.  (a) Draw a free-body diagram of the brick and identify each force acting on it. (b) Draw a free-body diagram of the cushion and identify each force acting on it.  (c) Identify all of the action reaction pairs of forces in the brickcushionplanet system.

Solution Verified by Toppr

The free-body diagrams are shown below.(a)     = normal force of cushion on brick.    = gravitational force on brick(b)    = normal force of pavement on cushion    = gravitational force on cushion    = force of brick on cushion(c)   force: normal force of cushion on brick reaction force:   force of brick on cushion    force: gravitational force of Earth on brick reaction.   force: gravitational force of brick on Earth.   force: normal force of pavement on cushion reaction.   force: force of cushion on pavement   force: gravitational force of Earth on cushion reaction.   force: gravitational force of cushion on Earth.   0 0
