Problemas de aplicación sobre Dinámica: 1.- Una bala de 12 g es acelerada desde el reposo hasta una velocidad de 700 m/s al recorrer 20 cm dentro del cañón de un fusil.
Suponiendo que la aceleración es constante, ¿Qué tan grande debe ser la fuerza aceleradora?
2.- Sobre un cuerpo cuya masa es 8kg y que se está moviendo con una velocidad de 3m/s, comienza a actuar una fuerza de 30N. ¿Cuál
será su velocidad y cuál el espacio recorrido cuando hayan transcurrido 8 segundos, si la fuerza se aplica en el mismo sentido del
movimiento del cuerpo?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
