Reflection Vector Drawing Vittorio needs to clean the dusty mirror hanging on the wall before he can use it, but he would like to clean as little of the mirror as possible.
Part A Vittorio would like to be able to see the logo on his shirt. Draw the incident and reflected rays showing the light from the logo reflecting off the mirror into his eyes. The rays should meet at the point on the mirror that needs cleaning.
Draw the vectors, for the reflected and incident ray, starting and ending at the surface of the mirror respectively. The location and orientation of the vectors will be graded.
A stationary destroyer is equipped with sonar that sends out pulses of sound at 35.000 MHz. If the speed of sound in seawater is 1.57 km/s, find the depth of the submarine
A basketball player passes the 0.60-kg basketball to another player with bouncing it off the court. The ball hits the court by a speed of 5.5 m/s at an angle of 67° from the vertical. If the ball rebounds with the similar speed and angle, what was th..
