Special relativity A.P.French 6.8 (is there solution manuals for this book?)

  1. Mar 18, 2012 #1
    1. The problem statement, all variables and given/known data
    A thrust-beam space vehicle works by bearing a sort of sail which feels the push of a strong steady laser light beam directed at it from earth. If the sail is perfectly reflecting, calculate the mass of light required to accelerate a vehicle of rest mass M0 up to a fixed value of θ.


    2. Relevant equations

    total energy is conserved, So

    E=mc^2-(1/2)(M0+m)v^2=0

    so, dE/dt=0 because energy is conserved.




    3. The attempt at a solution
    dE/dt=0-2/2(M0+m)vdv/t=0

    so (M0+m)=0, or m=M0.

    it is known that the rest mass of photon has energy, but it's not known whether it will apply a force on the object it hits, from the equation, there is a change in momentum, but not in force. in fact, the change is momentum and acceleration is zero.

    where can I find solution manuals for Special relativity A.P. French The M.I.T introductory physics series?
