ФИЗИКА A stone with a mass of 50 g was thrown from the surface of the Earth vertically upwards at a speed of 6.3 m/s. The trajectory of movement of the stone, as in the picture, is equal to the maximum lifting height of 2 m. The air resistance is not taken into account and g=10 N/kg. Determine the energy of the stone at points a, B, C and fill in the table.
