1. am=F-Fтрения
am=F-kmg
F=am+kmg
F=m(a+kg)
m=25000/2,1
m=11 904 кг.
3. начальная скорость - v(0)=15 м/с
конечная скорость - v(k) = 0 м/с (так как он в самом верху остановится, прежде чем падать обратно)
ускорение свободного падения - g=10 м/с^2
Найти: время (t)
из формулы ускорения g=( v(k) - v(0) ) / t выводим
t = ( v(k) - v(0) ) / g
t = (0 м/с - 15 м/с) / (-g) (-g - ускорение свободного падения направлено против вектора ускорения камня)
t = -15 м/с / -10 м/с^2
t= 1,5 с
ответ: t=1,5 с.
