What is the speed of the 40 kg box after it has gone up a ramp that's 3 meters tall? The box is initially going at V = 20 meters/second.

Would the equation just be 1/2 mv = 1/2 mv? Or do you incorporate gravitational energy which is = mgh?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

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.
