Let A= (3.0 m, 20 0 south of east), B = (2.0 m, north), and C= (5.0 m, 70 0 south of west).
a. Draw and label A , B, and C with their tails at the origin. Use a coordinate system
with the x-axis to the east.
b. b. Write A, B, and C in component form, using unit vectors.
c. c. Find the magnitude and the direction of D = A + B+ C.

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
