1. according to a newspaper account, a paratrooper survived a training jump from 1154 ft when his parachute failed to open but provided some resistance by flapping in the wind. allegedly he hit the ground at 101.75 mi/h after falling for 7 seconds. to test the accuracy of this account, you should first find the drag coefficient rho, assuming a terminal velocity of 101.75 mi/h and also that the resistance of the paratrooper falling through the air is proportional to his velocity. remember that the accleration due to gravity near the earth's surface is 32 ft/sec^2.
2. next, find the distance d fallen in 6 seconds.

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
