Abasketball player wishes to make a stunning last-second basket. with .8 seconds on the clock, she wants the ball to enter the hoop (height 3.05m) as time expires in the game. she shoots the ball with an initial speed of 7 m/s, from 2.1 meters above the ground.
1. at what angle (from the horizontal) does she shoot the ball?
2. draw qualitatively accurate position, velocity, and acceleration graphs for both dimensions of the ball's motion while it is in flight.

What happens to atoms and chemical bonds during a reaction?

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?
