Тело брошено вертикально вверх с начальной скоростью v0 (м/с) с начальной высоты h0 (м). Зависимость высоты h (м) тела над землей от времени полета t (с) задается формулой h = -0,5gt2 + v0+ h0. 1) Постройте график этой зависимости, если h0= 20, v0 = 15, g = 10.
2) Используя график, определите:
а) За какое время тело поднялось на максимальною высоту?
б) На какую максимальною высоту поднялось тело?
в) Сколько секунд тело падало вниз?
