a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
