En la figura se muestra una prensa hidráulica en equilibrio. Se sabe que S1 = 30 cm^2; S2 = 120 cm^2 . ¿Qué valor tendrá F2, si F1 = 100 N? (considerar pi=3,14)

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
