Homework Statement
Imagine that you are flying on an airliner on a long flight to Europe at a constant speed of 300 m/s
a) you throw a ball towards the back of the plane at 20 m/s. You then shine a beam of light towards the back of the plane. How will these two things-- the ball and light-- appear to move from the Earth's frame of reference
b) would you expect your watch to be affected by time dilation?
Homework Equations
Δtm = Δts/√(1-v2/c2)
The Attempt at a Solution
a) The ball moves at 300-20 = 280 m/s forward
The light moves at c-v
3x108-300=2.999997x108 Confused here, this is an inertial frame of reference so is the speed of light a constant 3x108 m/s or is 2.999997x108 correct?
b) The plane does not move fast enough for time dilation to be noticed but it is occurring. The watch would not be able to detect the significantly small change in time dilation
