Based on the speculations of Nicole Oresme, and on the equation relating spatial distance, time, initial velocity, and constant acceleration developed by the Mertonian Calculators, how far would you expect a falling object to travel in 4 seconds (falling from a spaceship towards the Earth, in the vacuum of space), starting at 0 feet/second, with constant acceleration (32 feet/sec2), and neglecting possible air friction? 64 feet 144 feet 256 feet 400 feet 576 feet

2. Suppose a space vehicle with a rest mass of 150,000 kg travels past the International Space Station at a constant speed of 2.6 × 108 m/s with respect to the I.S.S. When an observer on the I.S.S. measures the moving vehicle, her measurement of the space vehicle length is 25.0 m. a. Determine the relativistic mass of the space vehicle. b. Determine the length of the space vehicle as measured by an astronaut on the space vehicle.
