at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

come closer and become far apart and become steam/gas

more than, less

less than, more

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
