A person drops a cylindrical steel bar (Y = 1.70 x 1011 Pa) from a height of 1.30 m (distance between the floor and the bottom of the vertically oriented bar).  The bar, or length L = 0.63 m, radius R =0.55 cm, and mass m=1.30 kg, hits the floow and bounces up, maintaining its vertical orientation.  Assuming the collision is elastic (bounces) and no rotation occurs, what is the maximum compression of the bar?  The formula for stress is given by:

Vector A has magnitude of 13.5 and is 345o counter-clockwise up from the +x-axis.  What are the x- and y-components of the vector?

After an average acceleration of 3.39 m/s2 during 2.29 s, a car reaches a final velocity of 16.1 m/s.  Find the car’s initial velocity.

Osmotic back pressure can be found by:

A squirrel runs along an overhead telephone wire that stretches from the top of one pole to the next. The creature is initially at position xi = 2.91 m, as measured from the center of the wire segment. It then undergoes a displacement of Δx = -5.61 m. What is the squirrel\’s final position xf?

A 129-kg horizontal platform is a uniform disk of radius 1.61 m and can rotate about the vertical axis through its center. A 65.7-kg person stands on the platform at a distance of 1.07 m from the center and a 27.3-kg dog sits on the platform near the person, 1.31 m from the center. Find the moment of inertia of this system, consisting of the platform and its population, with respect to the axis.

A sport car’s bumper is designed to withstand a 2.0-km/h (0.56-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Using the definition of work, and the Work-Energy theorem, calculate the average force on a bumper that collapses 0.100 m while bringing a 900-kg car to rest from an initial speed of 0.56 m/s.

A block is attached to a spring which is resting on a frictionless table. The block is pushed into the spring, compressing it.  The graph shows the component of the force (in N) exerted by the spring back on the block versus the position of the block relative to equilibrium.  What is the energy stored in the spring when it is pushed back to a distance of 4.5 cm from equillibrium? 

In an anesthesiologist’s practice, which type of modifiers indicates the patient’s health status at the time of the administration of the anesthesia?

What does the red dot pictured next to an ICD-10-CM code indicate?
