16. (II) a) Calcule la fuerza Fm requerida por el músculo "deltoides" para mantener estirado el brazo mostrado en la figura 12-56. La

masa total del brazo es 3.3 kg. b) Calcule la magnitud de la fuer-

za F, ejercida por la articulación del hombro sobre la parte su-

perior del brazo y el ángulo (con la horizontal) en que actúa

unbalanced force

explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
