1. The problem statement, all variables and given/known data http://img256.imageshack.us/img256/5530/hwimgxd3.gif [Broken] A particle of mass 0.450 kg is shot from P. The particle has an initial velocity [itex]V_0[/itex] with a horizontal component of 30.0 m/s. The particle rises to a maximum height of h = 21.0 m above P. Assume that h2 = 62.0 m. Determine the horizontal and the vertical components of the velocity vector when the particle reaches B. 2. Relevant equations Ay = Asin[tex]\theta[/tex] ?? i think 3. The attempt at a solution Okay well I already know the horizontal component is still 30.0 m/s because no force is acting upon it. But I dont even know if I'm even using the right equation to solve for the vertical component.
