What is a parachute? And how does it work ?

Use all these term gravity, terminal velocity, force

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

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
