A basketball rolls off a deck that is 3.2 m from the pavement. The basketball lands 0.75 m from the edge of the deck. How fast was the basketball rolling? Seema lists the given values in a chart and determines that the unknown value is vx.

A 2 column table with 2 rows. The first column is labeled Given with entries delta Y, a Subscript y Baseline, delta x. The second column is labeled Value with entries 3.2 meters, negative 9.8 meters per second squared, .75 meters.
Which describes Seema’s error?

The y and x values are switched.
The unknown is , not vx.
The value for ay is not known.
The value of y should be –3.2 m.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
