Тело брошено вертикально вверх со скоростью 25 м/с. На какой высоте

E = Ek + Ep = (m/2)*v + 0 = (m/2)*v, где v = 25 м/с.

E = Ek + Ep = (m/2)*v + m*g*h,

E = E = (m/2)*v

Ek = Ep/3,

E = (Ep/3) + Ep = (4/3)*Ep = (4/3)*mgh = E = (m/2)*v,

(4/3)*mgh = (m/2)*v,

(4/3)*gh = v/2,

h = (3/4)*v/(2g) = (3/8)*(v/g)

g = 10 м/с,

h = (3/8)*(25/10) м = 23,4375 м
