Question

1. The x- and y-coordinates of a moving particle are given by two parametric equations.

x = [a]t² + t

y = 2 - [c] 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 12-ft tall streetlight at 5 ft/sec. How fast is his shadow increasing when he is 3 feet from the streetlight?
