Which is a safer car bumper in a collision: one that is flexible and retracts or one that is rigid? why? which is a safer car bumper in a collision: one that is flexible and retracts or one that is rigid? why? the retractable bumper, because softer things withstand collisions better. the rigid bumper, because it does not change shape so easily. the retractable bumper, because it extends the time interval of the collision, thus reducing the force exerted on the car.

What happens when the number of protons in an atom changes

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
