find the solution of the wave equation for a vibrating string of length (l)=10units with ends fixed .it is given that c^2=1,initial velocity is zero and initial deflection is u(x,o)=k(sinx-sin2x)

  • physics -

    it i'll be 60m

    as there is no external force acting except gravitational force ,do its path should be at the range of parabolic path

    range(R)=u^2sin(theta)/g

    here u=20,theta=45,g=10

    thus R=20^2sin45/10=4

    conservation of momentum m1d1+m2d2=md

    m/2*20+m/2*d2=m40

    d2=60

    the other piece will fall 60m far from origin
