An unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 52.0 km . To the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 21.0 m/s . If nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?

A spacecraft with mass 1500 kg is in a circular orbit at an altitude 200 km above the surface of Earth. A) Use the Law of Universal Gravitation and Newton's 2nd law for circular motion to derive and find the speed of the spacecraft in this orbit. B) How much mechanical energy does the spacecraft have in this orbit? C) How much work must the spacecraft engines perform to get it into the above circular orbit from the surface of...

On Apollo Moon missions, the lunar module would blast off from the Moon's surface and dock with the command module in lunar orbit. After docking, the lunar module would be jettisoned and allowed to crash back onto the lunar surface. Seismometers placed on the Moon's surface by the astronauts would then pick up the resulting seismic waves. Find the impact speed of the lunar module, given that it is jettisoned from an orbit 130 km above the lunar surface moving...

Question 3 1 pts A spacecraft with mass 1,976 kg is in circular orbit around Earth as shown with the green circle in the figure, at an altitude h = 608 km. At point Pin the orbit (see figure), the spacecraft reduces its speed by 4%, causing it to be in an elliptical orbit. What is the semi-major axis of the elliptical orbit in km? Reminder the radius of the orbit is the altitude plus Re, the radius of Earth....

Consider a Hohmann transfer from a circular parking orbit around Earth at 200 km altitude, to the Moon (distance center of mass Earth – center of mass Moon is 384,000 km; you can ignore the size of the Moon and the altitude of the target orbit around the Moon). The Moon orbits Earth in a circular orbit as well. Both orbits (parking,Moon) are coplanar. What is the velocity of the Moon,and what is the velocity of the satellite when reaching...

80.A spacecraft is approaching Mars after a long trip from the Earth. Its velocity is such that it is traveling along a parabolic trajectory under the influence of the gravitational force from Mars. The distance of closest approach will be 300 km above the Martian surface. At this point of closest approach, the engines will be fired to slow down the spacecraft and place it in a circular orbit 300 km above the surface. (a) By what percentage must the...
