Choose the false statement about a fly ball as it travels from a batter's bat to a center fielder who catches the ball. a. the ball speeds up as it falls. b. gravity affects the ball the entire time it is in flight. c. the ball continually slows down as it rises to its highest point. d. drag affects the ball's speed only on its way up to its highest point.

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.)
