A ball is rolling across the floor. Its motion can be described by the two vectors above 6m/s east and 3 m/s north. determine the ball’s true motion by finding the resultant of the vectors.

A12-kg bag of groceries is tossed onto a table at 4.0 m/s and slides to a stop in 2.2 s . modify the equation fδt=δ (mv) to find the force of friction.
