-If you were accelerated at the rate of 1ft/sec^2, how fast would you be going at the end of the day, month and year? How would your final speed for each time period compare with the speed of light? Repeat the problem (variation) only with acceleration of 32ft/sec^2. -Name and state laws and/or principles used
*20. Imagine driving down a street toward a traffic light. How fast would you have to go so that the red light (700 nm) would appear green (500 nm)? What fraction of the speed of light c (c = 300,000 km/s) is this velocity?
When parked, your car is 6.4 m long. Unfortunately, your garage is only 3.9 m long. How fast would your car have to be moving for an observer on the ground to find your car shorter than your garage? Express your answer using two significant figures. Part B When you are driving at this speed, how long is your garage, as measured in the car's frame of reference? Express your answer using two significant figures.
When parked, your car is 5.2 m long. Unfortunately, your garage is only 3.9 m long. Part A: How fast would your car have to be moving for an observer on the ground to find your car shorter than your garage? Part B: When you are driving at this speed, how long is your garage, as measured in the car's frame of reference?
You are standing on the ground observing the sky. Two spaceships A and B fly past you. Spaceship A is moving at a constant speed of 1000 m/s relative to the ground. Spaceship B is moving opposite to A at speed of 1000 m/s relative to the ground. Spaceship A fires a strobe light that sends out a pulse of light opposite to where it is heading. a) What is the velocity of spaceship A relative to spaceship B? b) What is...
You drive past a potential parking space in center city. Your new car is travelling at 85% the speed of light. If your car is 6.0 m long (which you measured the day you bought it) and you observe the space to be 3.0 m, should you try to park? Why is your friend on the sidewalk (who hasn't studied relativity) so sure that you can park? How does the situation appear to him?
A car is traveling at 12 m/s A. How fast would the car need to go to double its kinetic energy? B. By what factor does the car's kinetic energy increase if its speed is doubled to 24 m/s?
3. Calculate, for the judge, how fast you were going in miles per hour when you ran the red light because it appeared Doppler-shifted green to you. Take red light to have a wavelength of 650 nm and green to have a wavelength of 550 nm Throughout this homework assignment, you may use c to denote the speed of light in both your work and final answers without using its numerical value. (This is actually preferred unless the problem requires...
