Problem 7-6A particle of mass 0.500 kg is shot from Pas shown in the figure. The particle has an initial velocity ivGwith 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 (a)the vertical component of ivG, (b)the work done by the gravitational force on the particle during its motion from Pto B, and (c)the horizontal and the vertical components of the velocity vector when the particle reaches B.
