Aglass has circular cross sections that taper (linearly) from a radius of 4 cm at the top of the glass to a radius of 3 cm at the bottom. the glass is 18 cm high and full of orange juice. how much work is required to drink all the juice through a straw if your mouth is 5 cm above the top of the glass? use 1000 kg divided by m cubed for the density of orange juice and 9.8 m divided by s squared for the acceleration due to gravity.

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.
