Two horizontal curves on a bobsled run are banked at the same angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius curve is v. What is the safe speed on the larger radius curve?A) v/2B) v / 2C) 2vD) v2I shall answer it here so this can help other students outFirst, FN = mg/cosOn a banked curve, FNx is the only acceleration forceFNx = mv^2/rFNx = FNsinmg/cos * sin = mv^2/rcancel out the mass (m) and sin*1/cos is tangtan = v^2/rrgtan = v^2(rgtan) = v (this is the velocity for the smaller radius.)call larger radius velocity Xfor larger radius, it becomes 2r, so (2rgtan) = Xunderstand you can do xy = x * y(rgtan) * 2 = X ((rgtan) = v)v * 2 = X (where X is velocity with larger radius)

In this activity, you will create a mind map showing the different pathways that can be found in the Government & Public Administration cluster. A mind map is a sketch or diagram that you can design yourself to organize your ideas. It could look like a tree with different branches or a park with different paths! Whatever you decide, you will put each pathway on a different spot on your mind map.Under each pathway, you will give one example of a job found in each pathway.Write a short note beside the job, explaining where you might find this person.List at least one task that they accomplish to keep things running for us.

A gazelle is grazing while standing in a fixed location. When it's startled by a predator, the gazelle accelerates uniformly for 16.8 s until it reaches a speed of 21.9 m/s. The gazelle then runs in a straight line at constant speed for an additional 16.4 s. Finally, it uniformly slows to a stop at a rate of 1.8 m/s/s. What is the total distance traveled by the gazelle in meters
