A projectile is fired vertically upwards from the surface of the earth with a velocity Kve , where ve is the escape velocity and k < 1. If R is the radius of the earth, the maximum height to which it will rise, measured from the centre of the earth, will be (neglect air resistance)
  • a)
  • b)
  • c)
  • d)
Correct answer is 'B'. Can you explain this answer?
Verified Answer
A projectile is fired vertically upwards from the surface of the earth...
Initial PE = -GMm/R(KE)i = mV^2/2 = mk^2v^2/2v = (2GM/R)^1/2 (escape speed = (2GM/R)^1/2)so , (KE)i = k^2GMm/Rtotal energy initial = GMmK^2/R - GMm/R ..1 finally particle comes to rest after attaining a H height...now PE = -GMm/(R+H) (KE)f = 0total energy = -GMm/(R+H) ..2since mechanical energy is conserved so eq1 = eq2 -GMm/(R+H) = -GMM/R +K^2GMm/RH/R+H = K^2 H = RK^2/(1-K^2)
