Space debris left from old satellites and their launchers is becoming a hazard to other satellites. (a) calculate the speed of a satellite in an orbit 900 km above earth’s surface. (b) suppose a loose rivet is in an orbit of the same radius that intersects the satellite’s orbit at an angle of 90º relative to earth. what is the velocity of the rivet relative to the satellite

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

How would doubling the made of an object change the objects potential energy

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].
