PO3.09 friction problems
1-3) A teflon block of mass 5.00 kg slides to the right on a steel floor under the
influence of an external applied force that is directed toward the right and has
magnitude 3.00 N (as you might have due to the constant pull from a cord
attached to it, for instance). Enter all answers in standard units, and do not
include the units in the answer fields.
I) Calculate the magnitude of the normal force with which the floor pushes on the
block.
2) Calculate the magnitude of the frictional force acting on the block.
3) Calculate the magnitude of the acceleration this block is experiencing.
4-6) Take the same problem as before and add a second external force that
points in the same direction as the normal force from the floor on the block with
magnitude 8.00 N. Solve the same three problems and report following the same
guidance.
4) Calculate the magnitude of the normal force with which the floor pushes on the
block.
5) Calculate the magnitude of the frictional force acting on the block.
6) Calculate the magnitude of the acceleration this block is experiencing.
7) Consider a rubber block with mass 40.0 kg sitting at rest on a dry, flat,
concrete surface. Will a sideways applied force of 300. N from someone pushing
on the block be able to make the block accelerate? If the answer is yes, calculate
the magnitude of the acceleration. If the answer is no, calculate the magnitude of

the static frictional force. In either case, select the answer from the list that is
closest to the truth.
A) 0.6325
B) 2.595
