I need help on this, i need to finish this asap

prolly a beacuse the momentuem the car has increases while going down hill

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

float.

archimedes' principle

denser than mercury would sink in it
