As is known, astronauts in space can not be weighed in a bath scale. Instead, they determine their mass, oscillating in a great product. It assumes that an astronaut is in a space that is anchored in the spatial situation. A fellow astronaut pulls it and releases it starting a swing. The amplitude of growth as a function of time is shown in the figure. (a) what would be the quantity of the mass in the direction of 240 n / m? (b) what is the speed of the astronaut when the amplitude of growth is 1. 2 m? .
