- Heddy practices with first her bow and arrow. She hopes that her first arrow will hit the center of a target which is located at a horizontal distance of 7.00 m from the arrow's launch point. The target's center is located 1.50 m above the ground. Heddy shoots her first arrow with a launch velocity of 12.0 m/s directed 20 degrees above the horizontal. At the instant of its launch, the arrow is located 1.00 m above the ground, as shown in the figure. In the following, treat the arrow as a point particle (or a ball which has been pitched). In the following, assume that air resistance is negligible and that g=9.80 m/ 2. Target I 0.500 m I 0.500 m Target's 20 center 1.50 m 1.00 m 7.00 m 18. How much time would it take the arrow to travel a horizontal distance of 7.00 m? A. 0.583 s. В. 1.71 s. C. 0.869 s. D. 0.621 s. E. 0.419 s. 19. Which one of the following statements is correct? A. The arrow hits the ground before reaching the target. B. The arrow hits the target, 0.35 m above the…A projectile is fired from ground level at an angle of 35.0° above horizontal at a speed of 55.0 m/s. What is the speed of the projectile when it has reached a height equal to 50.0% of its maximum height?Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 39.0 m/s at an angle of 33.0° above the horizontal. (a) Assuming that the ball lands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. m (b) The second friend hits his golf ball with the same initial speed as the first, but the initial velocity of the ball makes an angle with horizontal that is greater than 45.0°. The second ball, however, travels the same horizontal distance as the first, and it too lands at the same height from which it was hit. What was the angle in degrees above horizontal of the initial velocity of this second golf ball? Ignore air resistance. ° above the horizontal
