1. On the diagram above, use a protractor and ruler to draw a vector to represent the initial velocity of the projectile. Begin the vector at point P, and use a scale of 1.0 centimeter 50. meters per second. 2. Determine the horizontal component of the initial velocity. 3. Explain why the projectile has no acceleration in the horizontal direction. [Neglect air friction.]
