Mr. Singleton leaves home at 6:45 am and arrives at Townschool at 7:30 am. His odometer reads 39,469 km when he starts his trip and reads 39,499 km when he arrives at
school. What was Mr. Singleton's average speed on his drive to school? Give your
answer in m/s.

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.
