Physics 101 Introduction to Mechanics 

February 20 Applications of Newton's Laws  



Nonzero
accelration motion
This class has an object moving with a constant acceleration
in a linear fashion. The uniform circular situations have a constant
acceleration, but the motion is not linear.
Write down all of the forces and then be sure to
include the "ma" term which is no longer zero. As always, we're simply
using Newton's Second Law.
A 65 kg person is standing on a bathroom scale in
an elevator moving downward. If the scale reads 720N, what is the
magnitude and direction of the elevatorís acceleration?
