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

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

intertwined around itself‚ but regardless of how big‚ fast‚ or gravity defying they are‚ they all use the same natural force – gravity. The more twisting‚ turning‚ flipping‚ and the faster a roller coaster goes‚ the more the coaster depends on the law of physics‚ not mechanics‚ to keep it moving. There is no onboard motor on roller coasters but they can still reach speeds that exceed the limits of a car on the parkway‚ while completing a curve‚ twist‚ rise‚ or plunge.
