HIGH-VELOCITY INJURIES Harland Hayes‚ University of Utah School of Medicine It should be no great surprise to find out that the most serious of injuries that occur in the back country are those that are associated when people are moving with speed. There are common sports that by their very nature require speed such as skiing where injuries don’t have to occur. However‚ there are other sports that demand deliberate even delicate moves‚ such as rock climbing‚ where speed gained from a fall

1) A 4-kg mass moving with speed 2 m/s‚ and a 2-kg mass moving with a speed of 4 m/s‚ are gliding over a horizontal frictionless surface. Both objects encounter the same horizontal force‚ which directly opposes their motion‚ and are brought to rest by it. Which statement best describes their respective stopping distances? (A) The 4-kg mass travels twice as far as the 2-kg mass before stopping. (B) The 2-kg mass travels twice as far as the 4-kg mass before stopping. (C) Both masses travel the

Motion in 2D Simulation Go to HYPERLINK "http://phet.colorado.edu/simulations/sims.php?sim=Motion_in_2D" http://phet.colorado.edu/simulations/sims.php?sim=Motion_in_2D and click on Run Now. 1) Once the simulation opens‚ click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When the ball is stopped there isn’t any changes

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

MYP 8 (1) Sabrina Group member: Lucy‚ Angel Research question: How does the air force affect the falling place? Hypothesis: If the air force is lower/higher than the falling place is closer/further because in some place air force let parachute fly more further/closer when the air force is lower/higher. Variables: Independent variable: air force. Dependent variable: distance of parachute (measure with ruler) Control variable: the

The physics behind SCUBA diving and the physical effects on the body. Scuba diving is a sport that many people enjoy but hardly understand the physics behind. The journey from the pressure of the atmosphere to the deeper depths of the seas is not just a trip that involves breathing air out of a tank and looking at fish. If we were to go on an imaginary journey beginning at the surface and traveling to the bottom of a 300 foot lake your body would under go a change in pressure nearly of 10 times
