Question
How do I do part e and f
![A block (with mass M) is resting on an inclined plane, and is attached to the wall by a cord (see figure). The block is
pulled by an applied force F (horizontal) on the lower side. The inclined plane is frictionless and makes an angle 0 with
the horizontal. Use g =
9.81m/s2.
(a) Draw a free body diagram for the block. Label and state all the forces on the block.
F: Applied force
(b) Write down all the forces in unit-vector notation in terms of their magnitudes (in variables) and the inclined angle 0.
F = F cos 0 î +F sin 0 j
(c) Find the magnitude of the tension in the cord (in terms of known variables: F,M and 0). [Use the fact that F = 0.]
