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:

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
