Such a tiring day.. tomorrow ill send Steven d answer… oh ya, if u wan to know d questions, here they r….
1. The mass of Mars is 6.37 x 10^23 Kg and its average
distance from the sun is 2.28 x 10^11 metres. (The
radius of mars is 3.43 X 10^6 metres).
a) calculate the smallest possible distance between
Mars and the Earth.
A spacecraft is travelling directly from Earth towards
Mars when two planets are at minimum distance
b) how far is the spacecraft from MArs when it
experiences gravitational force from two planets?
" F=Gm1m2/r^2 and g=GM/R^2
2. To a cyclist X travelling at 8 km/h due east the
wind appears to blow from the south. Another cyclist Y
travels at 16 km/h N30degreeW relative to X. The
direction of wind as experienced by Y is from west.
Calculate the speed and direction of the wind.
