A pilot claims to have seen a UFO moving initially at a speed of about 440 m/s in an easterly direction and then, in a time interval of only 1.0 s, turning 45 degrees and moving southeast at 440 m/s. Compute the UFO’s average acceleration during the turn.

Solutions

Expert Solution

eastward acceleration, a_e = (440 m/s - 440 m/s * cos45) / 1sec

= 128.87 m/s^2

southward acceleration, a_s = 440m/s * sin45 / 1sec

= 311.13 m/s^2

total acceleration a = = sqrt(a_e² + a_s²)

= sqrt(128.87² + 311.13 ²)

= 336.76 m/s^2

We’ve seen that Hume claims that words are used quite frequently that have no "definite idea" attached to them. One way for this to happen is for people to have no clear idea of what they are talking about when they use these words. In your view, to what extent is this true of words like 'God,' 'soul' and 'heaven'? Combined with the apparent fact that there are no sense impressions of these things, does this mean, as Hume suggests,...

We have seen that the standard deviation σ measures the spread of a data set about the mean μ. Chebyshev's inequality gives an estimate of how well the standard deviation measures that spread. One consequence of this inequality is that for every data set at least 75% of the data points lie within two standard deviations of the mean, that is, between μ − 2σ and μ + 2σ (inclusive). For example, if μ = 20 and σ = 5,...

I would have to agree that the shift is moving towards online advertising. Think about it, we have Netflix or on demand programming now where commercials are non-existent. However, we see ads all the time now online. If we go to watch a quick YouTube video on how to do something we are forced to watch a snippet of an ad. Even on social networking there are sponsored ads that are peppered through our feeds. Geo-targeting and data-opolies like Amazon...
