Light is the fastest thing in the universe, moving at 299,792,458m/s. For the fun of it, let’s assume an object was thrown at the speed of light straight up. Let’s also assume that only Earth’s gravity could slow it down, and acted with the same downward acceleration no matter how far away the object was. a.)How long would it take for the object to come to a stop? (please answer in days) B.)How far would the object have travelled in this time

Hello please help me with physics questions: Part A: given a velocity versus time graph, what does the area u see the curve to a point tell us? 1) the distance travelled by the object to that point. 2) the objects speed to that point. 3).The objects velocity to that point. 4). The object acceleration to that point.   Part B: given an acceleration versus time graph, what does the area under the curve to a point tell us? 1). The distance travelled by the object to that point. 2). The objects speed to that point. 3). The objects velocity to that point. 4). The objects acceleration to that point?   part C: A ball rolling rapidly along a tabletop rolls off the edge and falls to the floor. At the exact instant that the rolling ball rolls off the edge of the table, a second ball is dropped from rest from the same height as the table . The rolling ball hits the floor ? 1). Before the falling ball hits the floor 2). at the same time as the falling ball hits the floor. 3). After the falling ball…

Number 5 The USS Enterprise accelerates from rest at 100,000m/s2 for a time of four seconds. How far did the ship travel in that time?

The speed of light is 3 x 108 m/s.  If it takes sunlight 8 minutes to reach earth, how far away is the sun?

As a spaceship is moving toward Earth, an Earthling measures its length to be 403 m, while the captain on board radios that her spaceship's length is 624 m. Calculate the spaceship's speed relative to earth and supply the missing numerical factor below. __)c

6. A train is moving with a constant speed. The train moves 60 meters for every 1.5 seconds that elapses. a. Assume that we get 40 by dividing 60 by 1.5. What is the name that is commonly given to a quantity represented by this number 40? b. To denote the quantity completely, what additional information must be given besides the number 40? c. How would you interpret the number 40 in this instance? Your answer should mention distance and time. d. Use your interpretation (not algebra) to find the distance the train moves in 2.5 seconds.

1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to the earth. You may assume that both clocks can measure time accurately to many significant digits. a. Will the two clocks still be synchronized after one year? Explain your reasoning. b. Imagine that the speed of light was much slower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning, using a calculation.

The great astronomer Edwin Hubble discovered that all distant galaxies are receding from our Milky Way Galaxy with velocities proportional to their distances. It appears to an observer on the Earth that we are at the center of an expanding universe. The figure illustrates this for five galaxies lying along a straight line, with the Milky Way Galaxy at the center.  B) Using the data from the figure, calculate the velocity of galaxy 3 relative to galaxy 2 in km/s.   C) Using the data from the figure, calculate the velocity of galaxy 4 relative to galaxy 2 in km/s.   D) Using the data from the figure, calculate the velocity of galaxy 5 relative to galaxy 2 in km/s.   E) Using the data from the figure, calculate the velocity of galaxy 1 relative to galaxy 5 in km/s.   F) Using the data from the figure, calculate the velocity of galaxy 2 relative to galaxy 5 in km/s.   G) Using the data from the figure, calculate the velocity of galaxy 3 relative to galaxy 5 in km/s.   H) Using the data…

The motion of a cart can be represented by x(t)=(-2.5m/s)t-10.0m. At what time does this cart cross the origin? a)it crosses the origin t=4s after we start observing it b)It crosses the origin t=0s after we start observing it c)If it were moving the same way before we started observing it then it crossed the origin 4 seconds before we started counting.

A space probe with a diameter of 2.50m is moving past Saturn's moon Enceladus. An observational platform on Enceladus measures the shortest length of the ellipsoidal probe to be 1.25m. How fast is the probe moving relative to the moon? a) .999c b) .995c c) .957c d) .883c e)  .866c
