You’re driving to Carey Lake to get the last rays of summer when the light turns red at the Umtanum intersection. You just pass Koletty’s, so you know you know you are exactly 110 m from the intersection. If your reaction time is half a second and you were driving 20 m/s before the light changed, what acceleration will bring you to a stop right at the edge of the intersection? [-2 m/s2]

9.07 A laser beam aimed from the earth is swept across the face of the moon. Part A If the beam is rotated at an angular velocity of 1.45×10^−3rad/s1.45×10^−3rad/s, at what speed does the laser light move across the moon’s surface? ( 3.84 x10^8) Express your answer with the appropriate units. Part B If the diameter of the laser spot on the moon is 6.10 km , what is the angle of divergence of the laser beam? Express your answer in radians
Your roommate is playing a video game from the latest Star Wars movie while you are studying physics. Distracted by the noise, you go to see what is on the screen. The game involves trying to fly a spacecraft through a crowded field of asteroids in the asteroid belt around the Sun. You say to him, “Do you know that the game you are playing is very unrealistic? The asteroid belt is not that crowded and you don’t have to maneuver through it like that!” Distracted by your statement, he accidentally allows his spacecraft to strike an asteroid, just missing the high score. He turns to you in disgust and says, “Yeah, prove it.” You say, “Okay, I’ve learned recently that the highest concentration of asteroids is in a doughnut-shapedregion between the Kirkwood gaps at radii of 2.06 AU and 3.27 AU from the Sun. There are an estimated 109 asteroids of radius 100 m or larger, like those in your video game, in this region . . .” Finish your argument with a calculation to show that the number of…

While passing between Earth and the Moon, a spacecraft is momentarily located on the line connecting the centers of the two bodies and is at a distance of d = 101 km from a radio antenna on the surface of Earth. The distance from the antenna to the moon is denoted by dm. Part (a) Recall that the speed of light is 3.0 × 108 m/s. How long, in seconds, does it take for a signal from the spacecraft to arrive at the antenna on Earth? Part (b) Scientists on Earth send a command to the spacecraft, which immediately sends back a receipt confirmation signal. How long, in seconds, after the scientists send the command does it take before they learn it was received? Part (c) Scientists bounce a laser beam off the Moon and measure the two-way travel time to be 2.42 s. How far away is the Moon in meters?
How far does light travel in 90.0 second ?(c=3.00x 10^8 m/s)
The Tunguska event. On June 30, 1908, a meteor burned up and exploded in the atmosphere above the Tunguska River valley in Siberia. It knocked down trees over thousands of square kilometers and started a forest fire, but produced no crater and apparently caused no human casualties. A witness sitting on his doorstep outside the zone of falling trees recalled events in the following sequence. He saw a moving light in the sky, brighter than the Sun and descending at a low angle to the horizon. He felt his face become warm. He felt the ground shake. An invisible agent picked him up and immediately dropped him about a meter from where he had been seated. He heard a very loud protracted rumbling. Suggest an explanation for these observations and for the order in which they happened.
3. How long will it take light moving at 300,000 km/s to reach us from the sun? The sun is 150,000,000 km from earth.
11. Approximately how long does it take for light to travel 1 foot? a) 1 nanosecond b) 1 millisecond c) 1 microsecond d) 1 sec
Hi how can I do a sketch the situation given in this problem?
A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 575.5 nm had been shifted to green with a wavelength of 565.0 nm? (Accordingly, please enter your response to 2 significant digits. Use c = 3.00 108 m/s.)
