Taller de física mecánica 1. encuentre la magnitud y dirección de cada uno de los siguientes vectores. represente sus respuestas en un mismo plano cartesiano con ayuda de un trasportador. la dirección del vector debe especificar se con el ángulo en posición normal, es decir medido con respeto al eje positivo A. A = 2.5 ^ i 5.0 ^ j B. B =− 4.3 ^ i + 2.5 ^ j C. C =− 3.4 ^ i 3.8 ^ j 2. calcule el ángulo entre los pares de vectores que se muestran A. A = 2.5 ^ i 5.0 ^ j , B =− 4.3 ^ i 2.0 ^ j B. A =− 3.4 ^ i 3.8 ^ j , B =− 4.2 ^ i + 2.5 ^ j C. A =− 4.0 ^ i + 3.0 ^ j , B =− 6.0 ^ i + 8.0 ^ j 3. el torque de una fuerza aplicada en un punto determinado con el vector esta dado por t = r Encuentre el torque que ejerce una fuerza f = 2 ^ i + 3 ^ j 5 ^ k en torno a un punto ubicado con el vector posición r =−

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
