[LO 17.1, 17.6] A spacecraft is coasting toward Mars. The mass of Mars is 6.4x1023 kg and its radius is 3400 km (3.4x10° m). When the spacecraft is 7000 km (7x10ºm) from the center of Mars, the spacecraft's speed is 3000 m/s. Later, when the spacecraft is 4000 km (4x10° m) from the center of Mars, what is its speed? Assume that the effects of Mars' two tiny moons, the other planets, and the Sun are negligible. Precision is required to land on Mars, so make an accurate calculation, not a rough, approximate calculation. Start from a fundamental principle.

Hi, I need help with part 1. Kirchoff's laws must be used
Please answer the following question, parts a & b. Thanks.
Physical science Simplify please 1. Explain how the results from Parts 1 and 2 verify Newton’s Second Law. If heavier objects were accelerated by gravity at a greater rate, what result would you have expected in measuring the period of the two pendulums of the same length but with different masses for the bob? 2. How close were your results to the known value of g, 9.81 m/s2 based on your percent error? What kinds of errors could have resulted in the difference in your result versus the actual known value of g?
Whole of part b please
Please see attachment for full question. I would like some assistance with the approach for this. The Schwarzschild radius ?BH for an object of mass ? is defined as ?BH=2???2 where ? is the speed of light and ? is the universal gravitational constant. ?BH gives the radius of the event horizon of a black hole with mass ?. In other words, it gives the radius to which some amount of mass ? would need to be compressed in order to form a black hole. The mass of the Sun is about 1.99×1030 kg. What would be the radius of a black hole with this mass?
