si el módulo de la fuerza de atracción del sol sobre un planeta es igual a 4x1022 n. si la masa del sol se volviese 3 veces mayor y la distancia se redujera a la mitad, el módulo de la fuerza de atracción entre ellos sería:

Jason and alejandro lift a chair 2 meters into the moving truck using 150 newtons of force. it takes them 3 seconds to lift the chair how much power did they use

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].

The record distance in the sport of throwing cowpats is 81.1 m. this record toss was set by steve urner of the united states in 1981. assuming the initial launch angle was 45° and neglecting air resistance, answer the following. (a) determine the initial speed of the projectile. m/s
