Agroup of scientists is trying to launch an object into orbit, and the object is traveling at 6500 m/s. which best explains why the object will not successfully orbit earth? there is not enough air resistance to keep the object moving. there is not enough friction to keep the object moving. the object is not traveling fast enough to match earth’s curvature. the object is traveling too fast to match earth’s curvature.

Alow cost, low earth orbit (leo) satellite is to be fabricated at a university, for subsequent launch by rocket. what are the constraints and objectives for selection of a material suitable for the satellite bus (i. e. the structure)? explain each in brief. (15 marks) b)suggest sources of data which could support the selection of materials for applications in space. (5 marks) c) set weights for the objectives listed in (2a) using the digital logic method. (5 marks)

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
