1. In a project in PE (let's assume this) you were asked to throw a golf ball from the roof of a 22.3 m tall house with an initial velocity of 14.0 m/s magnitude and directed at an angle of 50.3° above the horizontal. (a) What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. (b) What is the answer for part (a) if the initial velocity is at an angle of 50.3° below the horizontal? (c) If the effects of air resistance are included, will part (a) or (b) give the higher speed? (Non-anonymous questionO)
