a fully loaded saturn V rocket has a mass of 2.9*10 to the power of 6 Kg. Its engine provides a thrust of 3.3*10 to the power of 7N(down). Determine its weight (force due to gravity) as it stands on a launching platform
TMI - we don't need to know about how powerful its rocket is. Its weight
w = mg = 9.81 * 2.9*10^6 N
