An astronaut has a mass of 70kg. The force of gravity on the Moon is approximately 1.5N/kg.
Calculate the weight of the astronaut when they are on the Moon.

Weight = N

Which planet do you think would be easiest for humans to colonize some day?

What quantity do units represent in value

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
