This vessel will tend to be bluish or purple from the color of the blood within

The ____________ arteries are most often used to inject the legs in cases of complete autopsy.

Nerves will do this when cut

Ways to improve distribution in the congested heart case include: (Please choose all that apply)

Force F is applied to an object of mass {m}-kg and moving at velocity of 2.0 m/s.  Find the impulse (in units of Ns) on the object during the 14 second interval.

A child of mass {m} kg tries to cross a river by swinging from a vine. The vine is 10.0 m long, and his speed at the bottom of the swing is 7.00 m/s.  What is the tension (in units of N) in the vine at the lowest point?

A Lazy Susan (turning tabletop) has radius 0.750 m.  An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s.  What is the value of the apple’s tangential acceleration at 3.00 second in m/s2? Enter units as “m/s^2”

A Lazy Susan (turning tabletop) has radius 0.750 m.  An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s.  What is the value of the apple’s centripetal acceleration at the 3.00 second in m/s2? Enter units as “m/s^2”

A girl of 50.0-kg skating at 10 m/s crashes into another girl of mass 35.0-kg moving in the same direction at 8.0 m/s.  Assuming the impact lasts 0.15 s, after which they move together, how fast (in units of m/s)  are they moving immediately after crashing?  

Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (3.0, 0.0) m, 3.0 kg at (0.0, {y1}) m, 4.0 kg at (0.0, 0.0) m and a fourth object of 8.0 kg at (2.0, {y2}) m.  Find the y coordinate (in m) of center of gravity for this configuration.
