A cart with mass m = 20 kg is initially moving horizontally with constant velocity 0.8 m/s, when it strikes a mechanical “snubber” device that consists of a plate supported by two parallel springs (each with stiffness k = 1000 N/m), and a single damper (dashpot) with...
How would I find Jupiter's equatorial rotation period when it begins to tear the planet apart?
Is it true that if the centrifugal force is greater than the gravitational force the material can be torn apart?
If this is right, can I just set up an inequality for the centrifugal force >...
