Question: You are the science officer aboard the starship Enterprise, leading a scientific exploration of a neutron star. Your mission is to send a set of two robotic observation probes near the neutron star's surface to measure local conditions. The probes have a mass of 10 kg each and are linked by a 1 m high tensile steel cable (breaking tension 3.5 x 104 N). To perform their work, the two probes must be oriented such that one probe is always directly above the other. Assume that the neutron star has a 10 km diameter and 2 times the Sun's mass. What is the minimum altitude the probes can achieve above the neutron star's surface without snapping the connection cable?
Your mass is 50 kg. Suppose you are standing on a scale in an elevator that starts moving up and increases its speed at the rate of 3 m/s every second. What would be the reading on the scale?
