Realicen la siguiente actividad: a) Tomar un resorte y fijarlo a una tabla o la pared. b) Colgar 5 objetos pequeños al resorte, como una goma, un lápiz, una regla, celular Etc c) Marcar hasta dónde llega el resorte cada vez que le agrega un cuerpo. 1) ¿Qué observa cada vez que agrega un cuerpo? 2) ¿Qué relación hay entre el estiramiento del resorte y la masa de los cuerpos?

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
