Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 60 km/h and the other is moving at 40 km/h. In how many hours will they meet?

Calculate the speed (in m/s) of an electron and a proton with a kinetic energy of 1.15 electron volt (eV). (The electron and proton masses are me = 9.11 ✕ 10−31 kg and mp = 1.67 ✕ 10−27 kg. Boltzmann's constant is kB = 1.38 ✕ 10−23 J/K.)   (a) an electron m/s (b) a proton   m/s (c) Calculate the average translational kinetic energy in eV of a 3.09 ✕ 102 K ideal gas particle. (Recall from Topic 10 that  1 2 mv2 =  3 2 kBT.)   eV

On an alien world, they measure distance in fleeps and time in florps. If 1.6 fleep =1 m and 5.2 florps = 1 second, how many fleeps/florps is in 10 m/s? How many m/s^2 is 10 fleep/florps?

Two electrons are brought close together, to a distance of 75 pm apart. They are then both released from rest, accelerating and travelling away from one another. When the two particles are very far apart, how fast will they be going, in m/s?

1. A rocket flies toward the earth at c, and the captain shines a laser light beam in the forward direction. Which of the follow- ing statements about the speed of this light are correct? (There may be more than one correct answer.) A. The captain measures speed c for the light. B. An observer on earth measures speed e for the light. C. An observer on earth measures speed c for the light. D. The captain measures speed c for the light.

A cosmic ray particle is released from an exploding star that is 2600 Light Years from Earth. If the particle traveled at 98% the speed of light, how far did it travel in its own frame of reference before hitting Earth?

A clock is moving at v =(4/5)c. c is the speed of light. The clock passes our clock when both clocks read t = 0. When the moving clock reads t = 30 s, what will the clocks in our frame read?

A spaceship travels at a constant speed from earth to a planet orbiting another star. When the spacecraft arrives, 13 years have elapsed on earth, and 8.0 years have elapsed on board the ship. How far away (in meters) is the planet, according to observers on earth? Number i ap Earth time Ship time Spaceship departs earth Units Earth time -9 Ship time Spaceship arrives at distant planet

A pirate starship in the distant future is being chased by the space police. The pirates are traveling at 1273 km/h while the police are traveling at 1431 km/h. The pirate ship needs 25 minutes to turn on its faster-than-light drive so it can jump into hyperspace to escape.   How long, in minutes, will it take the space police to catch up to the pirates if they are 50 km away from one another? min   Will the pirates be able to escape?

The speed of light is about 3 x 108 meters per second. The Millennium Falcon is traveling from Earth to Mars at the speed of light. The distance between the Earth and Mars fluctuates between 5.46 x 10¹0 meters and 4,01 x 10¹¹ meters. If the day the Millennium Falcon makes the "Mars Run," the distance is 2.25 x 10¹¹ meters, how long will it take them? Note: distance = rate time, and time = distance/rate Express your answer in scientific notation. Use for the multiplication. seconds Convert your answer to minutes. Include at least 3 decimal places in your answer, which can be expressed in standard notation. minutes Suppose the Millennium Falcon flies for 5 hours at the speed of light. How far will they travel? Express your answer in scientific notation. meters
