G A 1.5 kg projectile is fired from the edge of a 20-m tall building with an initial velocity of v0 = 45.6 m/s directed 30° above horizontal. The projectile rises to point P and then lands on ground at Q. (a) Find the flight time of the projectile as it lands at Q. (b) Calculate gravitational potential energy of the projectile at point P. (c) Compute kinetic energy of the projectile at point R, which is at the same height as the edge of the building. (d) Determine the magnitude and direction of impulse the projectile impacts on the ground.
