A satellite orbits around a moon with a mass of 2.62 x 1022 kg in a approximately circular orbit. The satellite has a roughly constant speed of 423 m/s. What must be the distance between the center of the moon and the center of the satellite in meters? Answer in standard, floating notation, not scientific notation.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
