An 89 kilogram person needs to start sliding their waxed skis on snow, starting from rest. Calculate the force of
static friction that must be overcome for the skis to begin sliding. Show all work, including equations, values
with units, and substitution into the equation(s). [hint: remember to get weight first]

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.
