Dik: h = 45 m.
g = 10m/s^.
Dit: kecepatan dari roller coaster ketika sampai didasar lintasan?
jawaban:
V = g x h
V = 10 x 45
V = 450 m/s.
maaf jika salah.
m.g.hA + 1/2.m.C^2 = m.g.hB + 1/2.m.vB^2
m.450 + 1/2.m.C^2 = 0 + 1/2.m.vB^2
450 + 1/2.C^2 = 1/2.vB^2
450 = 1/2.(vB^2-C^2)
900 = (vB-C).(vB+C)
vB = 900+C atau 900-C
