La base de la escalera está a una distancia de <picture><source srcset="https://s3.amazonaws.com/prealliance-textbook-qa.oneclass.com/qa_images/homework_help/question/qa_images/456837167226393/question/1.webp?img=f914d7c64e956d2cc034f4840657b068" type="image/webp"><img src="https://s3.amazonaws.com/prealliance-textbook-qa.oneclass.com/qa_images/homework_help/question/qa_images/456837167226393/question/1.png?img=a1a6dd2835250aa534dfa34a00c9e77d" data-mlang="latex" data-equation="6m"></picture>  de la pared. ¿Qué altura alcanza la escalera sobre la pared?

Una escalera de 4 metros de longitud esta apoyada sobre la pared de una barda. Inicialmente la base de la escalera está a un metro de la pared y se desliza alejándose de la pared a una velocidad constante de <picture><source srcset="https://s3.amazonaws.com/prealliance-textbook-qa.oneclass.com/qa_images/homework_help/question/qa_images/011816854973695/question/0.webp?img=b759517e081e5492192a17266131d4d7" type="image/webp"><img src="https://s3.amazonaws.com/prealliance-textbook-qa.oneclass.com/qa_images/homework_help/question/qa_images/011816854973695/question/0.png?img=1d48dae829e1683b0b963bd14fbd2bd2" data-mlang="latex" data-equation="0.5%20m%2Fs"></picture>. ¿Cual es la velocidad del extremo superior de la escalera cuando el extremo inferior se separa un metro más de la pared?

De acuerdo con la imagen calcula la magnitud de la resultante (r) de la suma de vectores.
