5. A truck left a diner at 1:00 p. m. and drove 360 km to Jersey City. The truck arrived at 7:00 p. m. A car left the same diner at 2:00p. m. and drove to Jersey City at an average
speed of 80 km/h
a. How fast did the truck travel?

b. Which vehicle got to Jersey City first?
6. An Arctic tern can fly 85 km/h for 24 h straight. How far can it fly before landing?

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.
