A cars engine applies 7,500 N of force to accelerated it over 45 meters. Calculate the final velocity of the car (m = 1, 400 kg) if it started from rest.

scientific laws are the result of testing theories and proving them to be facts.

gas and liquid

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
