**1. A path is defined by the function y=1/20 x^2. One instant x=10m and y= 5 m the speed is 6 m/s and increasing at 2 m/s^2.**

a)Find the directional angle of the velocity from the horizontal?

The answer is 45 degrees

b)What is the radius of curvature of her path at this instant?

The answer is 28.28 m
