EMBRY RIDDLE MATH112 Module 5 - Discussion: Application CIN Problems

In the discussion area, solve your two custom application problems using the concepts you have learned. Apply your CINs in the bracketed spaces (the first digit is [a], the second digit is [b], and so forth.)

1. The x- and y-coordinates of a moving particle are given by two parametric equations..
   
   $x=\left[a\right]t^2+t$
   $y=2?\left[c\right]t$
   Find the magnitude and direction of velocity at t = 3 sec. Distance is measured in meters. Round your answers to one decimal place and don't forget to use the degree symbol.
   
   
2. A 6-ft tall man walks away from a [a]*[c]-ft tall streetlight at [b] ft/sec. How fast is his shadow increasing when he is [e] feet from the streetlight?
