What body postures and physical behaviors might be suitable to combat the effects of sustained strong accelerations?

Solution Preview

Sustained strong acceleration can be damaging to the body particularly if the force of the acceleration is too localized on one particular area or is otherwise not well distributed. Typically, in situations where an individual must undergo this type of physical duress, a special seat or cradle is used which has been ...

Solution Summary

Discussing the effects of strong acceleration on posture and the human body.

Please show your work clearly as I need to understandthe solution well.
Two blocks are connected by a light rope. An upward force of 220 N is applied upward on the upper block as shown in the attachment.
a. Draw a free-body diagram for each block indicating all forces exerted.
b. What is theacceleration of the system?

1) If you travel 1 mile AT THE SPEED OF 1000 mi/h, and another mile at the speed of 1 mi/h, what is your average speed?
2) A body with an initial velocity of 8m/s moves with constant accelerationand travels 640m in 40sec. What is its acceleration?

If a body is subjected to several forces, we must first find the net force on thebodyandthen apply F=ma to determine its acceleration.
For instance: A pail of water of mass 20 kg is being lifted by a rope from a well. It is ascending with an acceleration of 2 m/s^2. Determine tension in the rope.

This graph is for understanding the concepts of variable velocity, uniform velocity, uniform acceleration, negative acceleration, displacement and average velocity of a body moving along a straight line.
Answer the following questions:
a. What is the velocity of the car at 2, 8, 16 and 20 s?
b. What is theacceleration of t

A train slows down as it rounds a sharp horizontal turn, slowing from 90 km/h to 50 km/h in the 15 s that it takes to round the bend. The radius of the curve is 150 m. Compute theacceleration at the moment the train speed reaches 50 km/h.

I constructed a fairly simple experiment related to curvlinear motion. The experiment involved a small metal ball that rolls off a table and lands on the floor. I used the edge of table as the Y direction.
I timed the trial run from the of the edge of the table and when the ball hits the floor. I know X (total of all time thr

1.Theacceleration of a freely falling body is not exactly the same everywhere on Earth. For example, in the Galapagos Islands at the equator, is 9.780 m/s2, while at the latitude of Oslo, Norway, it is 9.831 m/s2. Why does theacceleration differ?
2. Assume that as a car brakes to stop it undergoes a constant acceleration (d

1. Balls A, B, and C all start at the same height above the ground. Ball A is dropped. Ball B is thrown horizonatally to the right at 5 m/s. Ball C is thrown horizontally to the left at 15 m/s. What is the order that they hit ground and why?
2. Explain why, when traveling in a circle, theacceleration is toward the center of

On my last test, there is a question: an object with a mass of 5kg is acted upon by 4 separate forces that each have a magnitude of 10N. I understand that there could be different resulting accelerations of the object but i don't understand why or how which is why i got this answer wrong. In fact, i was totally lost. What are th
