Мировое потребление энергии составляет примерно 3·1020 Дж в год. Сколько дейтерия в секунду потребовалось бы сжигать в термоядерных реакторах для обеспечения всех современных энергетических потребностей человечества

aX = -0,57 м/с^2
Объяснение:
дано:
вектор v0 = 4 м/с
t = 7 с
вектор v = 0
найти:
aX
вектор v = вектор v0 + вектор a × t
пусть X - ось, вдоль которой движется автомашина:
проекции на направление движения, то есть на ось X:
vX = v0X + aX × t
автомашина тормозит, то есть движение равнозамедленное,
проекция ускорения, aX, отрицательная: (ускорение направлено в противоположную движению сторону)
aX × t = vX - v0X
aX = (vX - v0X) / t
vX = 0, v0X = 4 м/с (автомашина движется горизонтально)
aX = (0 - 4) / 7 = -4/7 = -0,5714 = -0,57 м/с^2
