From the side
view,video a volunteer walking at a slow pace, a normal pace, and a
fast pace. Review the video several times, and construct a chart
that characterizes the differences in lower extremity kinematics
among the three trials. Explain what differences in muscle activity
are associated with the major kinematic difference

Jim is lifting weights. Holding a 20lb weight down by his side,
he bends his arm at the elbow, contracting his bicep, and holds the
position until he reaches muscle fatigue. Briefly describe how the
Henneman Size Principle relates to this example. List the steps of
muscle fiber recruitment necessary for the initial lift and
subsequent fatigue. Include a short summary of the muscle fiber
types, and the properties that contribute to the speed of
contraction, recruitment pattern and metabolic...

A.) A weight lifter bench presses 185 lbs, lifting the weights
from chest position (2.17 feet above ground), 1.80 feet above with
extended arms. How much work has been performed?
B.) What energies (if any) are present at initial chest
position?
C.) What energies are present (if any) at final position while
weights are held briefly?

(a) Light from distant objects, such as stars, are imaged by a
single lens. Assuming the focal length of the lens is 10 cm and the
aperture size is 2 cm, what is the minimum resolvable angle? Write
every step. (b) The same lens is used for imaging an amplitude
grating. What is the minimum grating spacing that will yield any
intensity variation(s) on the image plane using (i) coherent and
(ii) incoherent illumination? Be very specific in your answer...
