The speed of light in some other universe is 30 m/s. You want to
cover a distance of 100 m in 10 s (as measured on your watch) at a
constant speed.
a. How fast should you run?
b. How long did it take you to cover that distance according to an
observer at rest with respect to the track? (Carry four sig figs
throughout the calculation).
Homework Answers
a)
v = d/ t = 100 / 10 = 10 m/s
======
b)
considering time dilation
t = to / sqrt ( 1 - v^2/c^2)
10 = to / sqrt ( 1 - 10^2/30^2)
to = 8.16497 s
=======

A) Imagine that in another universe the speed of light is only c = 100 m/s. A person traveling along an interstate highway at 120 km/h ages how much slower than a person rest? B) Imagine the same universe as in part A. An airplane that is 40 m long at rest and flies at 300 km/h will appear to be how long to an observer at rest?

Which of these statements are true? The speed of light is approximately 299,792,458 m/s and is uncertain to about 1 m/s The speed of light is the same seen by any observer anywhere in the universe If you are driving along at 100 km/hr, the light leaving your headlights is moving away from your car at 100 km/hr (0.0277 km/s) plus the speed of light, The speed of light is exactly 299,792,458 m/s
Two rockets A & B fly past an observer. "A" moves at constant speed 1000 m/s relative to ground, "B" moves at constant speed 1000 m/s relative to ground and opposite of rocket A. Rocket A sends light opposite to where it is heading.
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 throw a rock with an initial speed of 30 m/s and an angle of 50 degrees with respect to the vertical. The field you are on is however not horizontal but is inclined by an angle of 10 degrees with respect to and above the horizontal. Choose a coordinate system whose origin is located where the rock is thrown, and a rotated system such that the positive y axis is positive at an angle of 100 degrees measured counterclockwise...

A student is running at her top speed of 5.0 m/s to catch a bus, which is stopped at the bus stop. When the student is still a distance 38.8 m from the bus, it starts to pull away, moving with a constant acceleration of 0.167 m/s2 . A. For how much time does the student have to run at 5.0 m/s before she overtakes the bus? B. For what distance does the student have to run at 5.0 m/s...
