A Crew Dragon with a mass of 12,519 kg is launched from the Kennedy Space Center. It is accelerating from rest to an orbital velocity to 7,800 m/s. Which of the following would be equal to the pull of Earth on the capsule? (1 point) The gravitational pull of the sun on the capsule

The gravitational pull of the capsule on Earth

The push of air resistance on the capsule

The push of air resistance on Earth

An astronaut is doing a spacewalk on a long tether at 0.05 km away from an orbiting satellite. His spacesuit includes a very sensitive gravitometer, which indicates the gravitational force acting on the astronaut and his spacesuit from the satellite is 3.34 E−8 N. If the mass of the astronaut and his suit is 250 kg, what is the mass of the satellite if G = 6.67 E−11 N*m2/kg2? (1 point)

4,000 kg

5,000 kg

6,000 kg

7,000 kg

An astronaut on the ISS is doing an experiment with two puffy Cheetos inside a carefully sealed container. A charge of 1.2 E−5 C is place on the first Cheeto. The second one receives a charge of 2.5 E−6 C. The force acting on the first Cheeto is 5.73 E−1 N. What is the distance between the Cheetos if k = 8.99 E9 N*m2/C2? (1 point)

40 cm

49 cm

60 cm

70 cm

At its closest distance from Earth, the moon experiences a gravitational force of 2.22 E 20 N. The mass of the Earth is 5.97 E24 kg. The mass of the moon is 7.35 E22 kg. What is the distance between the Earth and the moon at that point if G = 6.67 E−11 N*m2/kg2? (1 point)

1.32 E 4 km

3.63 E 6 km

3.63 E 8 km

1.32 E 17 km

Tom travels to the moon for NASA. While on the moon, the total weight of Tom and his lunar exploration suit is 224 N. His suit has a mass of 50 kg. The acceleration due to gravity is 9.81 m/s2 on Earth and 1.67 m/s2 on the moon. What would his weight be on Earth without the heavy suit? (1 point)

490 N

830 N

987 N

1304 N

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° 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.)
