Homework Help: Projectile question involving Law of Conservation of Energy

  1. Nov 8, 2006 #1
    A particle of mass 0.500 kg is shot from point P, 60 m above the ground. The particle has an initial velocity Vi, with a horizontal component of 30.0 m/s. The particle rises to a maximum height of 20.0 m above P. Using the Law of Conservation of Energy, determine the vertical component of Vi.
