Consider the system shown below. Block A (mass 8 kg) is connected to block B (mass 2 kg) by a horizontal string that passes over a massless, frictionless pulley. a. Draw and label all forces acting on blocks A and B. b. Draw a free–body diagram for each block c. Determine the acceleration of the system d. Determine the tension on the string.

A pulley of negligible mass is attached to a block weighing 504
N. A person uses the rope and pulley system illustrated in the
figure to lift the block at a constant velocity. The pulleys and
rope are all ideal.
F_G=____________ ?
A. Draw the free body diagram for the block. (Observe that three
are two rope segments pulling on the block.)
B. Apply Newton's first law and determine the tension in the
rope, and thus, the...
Since 1967, Tractor Pull
competitors from around the country have met at the Wood County
Fairgrounds
in Bowling Green, Ohio, for the National Tractor Pulling
Championship (www.pulltown.com). The tractor
or truck attempts to pull a heavy weight (called the
“sled”) as far as possible, up to the length of the track
(320 feet).
You are part of the first ever Penn State Tractor Pull team,
which will be competing in the
National Tractor Pulling Championship. As a physics student, the...
1. According to the paper, what does lactate dehydrogenase
(LDH) do and what does it allow to happen within the myofiber? (5
points)
2. According to the paper, what is the major disadvantage of
relying on glycolysis during high-intensity exercise? (5
points)
3. Using Figure 1 in the paper, briefly describe the different
sources of ATP production at 50% versus 90% AND explain whether you
believe this depiction of ATP production applies to a Type IIX
myofiber in a human....
