- the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angle of 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot? the officials in dublin decided to add a goal post to "kick O coin" 300 meters away and so many 33 meters high. would O'Malley's kick have cleared this goal post?How does the acceleration vector change throughout a cannonball's trajectory? Vo = 18 Height = 0 Projectile angle = 30 degrees Select 3 correct answer(s) The y-component of the acceleration is constant. The x-component of the acceleration the projectile is zero. The acceleration vector is pointing downward. The magnitude of the acceleration increases as the projectile rises and decreases as it is coming down. The y-component of the acceleration of the projectile is zero at the maximum height.A catapult is placed 100 feet from the castle wall, which is 35 feet high.
