The use of force to move an object is BLANK .

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.

Aman walks foward on a bus. to a stationary obserrver, the bus moves east at a speed of 13 m/s if the man moves 0.7 m/s east relative to the bus. what is his velocity in the frame of reference of a stationary observer?

2(a): determine expressions for its acceleration ax(t), velocity vx(t), and position x(t), given that its initial acceleration, velocity, and position are ai, vi, and xi, respectively. (use any variable or symbol stated above as necessary.)
