What's the answer for a and b
Worksheet #2.
GROUP:
r-axis is horizontal and y-axis is vertical.
1. A 10 pound block is resting on a ramp that is 45 degrees from horizontal. Assume
a) Give the components of the vector F representing gravitational force on the block.
b) Give the components of the unit vector, which we will label u the goes down parallel
to the ramp?
c) Give the components of the unit vector, which we will label u, that points up per-
pendicular to the ramp?
d) Compute ProjuF. What is its physical interpretation?
e) Compute Proju F. What is its physical interpretation?
f) Assume there exists friction in this model. Draw a complete force diagram.
