Question1
All through a balloon ascension, wearing an oxygen mask, you calculate the weight of a calibrated 5.50-kg mass and find out that the value of the gravitational field strength at your location is 9.792 N/kg. How high above sea level, where gravitational field strength was measured to be 9.803 N/kg, are you situated?
Question2
You encounter a moving walkway that is 87 m long and has the speed of 2.2 m/s relative to the ground. How long would it take you to cover the 99 m length of walkway if, once you find on the walkway, you straight away turn around and start walking in the opposite direction with a speed of 1.5 m/s relative to the walkway?
