Acar traveling at 69 km/h hits a bridge abutment. a passenger in the car moves forward a distance of 65 cm (with respect to the road) while being brought to rest by an inflated air bag. what magnitude of force (assumed constant) acts on the passenger's upper torso, which has a mass of 47 kg?

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.
