A man sets out to travel from A to C via
B. From A he travels a distance of 8 km on
a bearing N30°E to B. From B he travels a
further 6 km due east.

a Calculate how far C is
i north of A
ii east of A.
b Hence, or otherwise, calculate the
distance AC correct to 1 decimal place​

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
