A constant horizontal force a pushes a 4.40kg FedEx package across a frictionless floor on which a xy coordinate system has been drawn. The package's x and y velocity components versus time t.
Most of the motion generated by joints in the human body are examples of levers. An example of a third class lever is the forearm; the force which generates the motion is located in between the pivot point and the resistance force.
Steel Piano string, The lowest note on a grand piano has a frequency of 27.5 Hz. The string is 2 m (more or less; let's just assume it is exactly 2.000 m) long, and its tension is 1000 N (again, more or less, so let's say it's exactly 1000 N).
