Un tren de alta velocidad en reposo comienza su trayectoria en linea recta con una aceleracion constante de a= 0,9m/s a la 2 calcula la velocidad (en kilometros por hora) que alcanza el tren a los 5 minutos Ayuda

like poles repel so keep pushing north to north and repels funny to see this

the force on the thing and the distance the force moves the thing

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
