3. A 45,000 kg rocket is at rest lying on the ground pointing westward. The rocket engines are touching a 2,300 kg mobile cart that is also at rest pointing in the other direction. When the rocket engines fire an impulse is
produced from 840,000 N of force for a period of 1.3 seconds.
a. Solve for the impulse (J = Fxt). This is also the change in momentum.
b. What is the final speed of the rocket? [ Ap = m(vp-v) ]
C. What is the final speed of the cart? (both the rocket and the cart have the same change in momentum)

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?

Listed below are the measured radiation absorption rates (in w/kg) corresponding to 11 cell phones. use the given data to construct a boxplot and identify the 5-number summary. 1.16 0.85 0.69 0.75 0.95 0.93 1.18 1.17 1.42 0.54 0.57 the 5-number summary is nothing, nothing, nothing, nothing, and nothing, all in w/kg. (use ascending order. type integers or decimals. do not round.)

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
