Complete the passage to describe polarization.
unpolarized light is filtered by a polarizer that has a vertical plane, allowing light with oscillations to pass through and blocking light that oscillates in other directions.
then, another polarizer that has a plane is used to block the polarized light.

Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 57 t − 16 t 2 feet. find the time t when the ball will be traveling upward at 14.25 feet per second.
