12) A golf ball is hit at an angle of 45° above the horizontal. What is the acceleration of the golf ball at the highest point in its trajectory? [Neglect friction.] (A) 9.8 m/s2 upward (B) 9.8 m/s2 downward (C) 6.9 m/s2 horizontal (D) 0.0 m/s2. 13) A ball is thrown horizontally at a speed of 24 meters per second from the top of a cliff.
The optimum angle for a simple trajectory problem to achieve maximum distance is 45 degrees. However, with golf, because of the spin on the ball, air/wind resistance, and other factors, this angle is generally less (for maximum distance) and varies from one situation to another. Here is a diagram of these three keys to maximize distance:
Aug 05, 2019 · Each golf club is designed to perform differently than the others. On one end you have your highest lofted clubs. These clubs have higher launch angles, as much as 64 degrees of loft (possibly more), while a driver can have as little as 6 degrees ...
f. The ball’s vertical speed immediately before contact with the ground: ‐3 m/s g. The ball’s velocity throughout the filght: ‐9.8 m/s2 2) A rugby player attempts a kick after scoring a try. The ball was kicked at an angle of 60
A golf ball is hit at an angle of 45° above the horizontal. What is the acceleration of the golf ball at the highest point in its trajectory? [Neglect friction.] (1) 9.8 m/s2 upward (2) 9.8 m/s2 downward (3) 6.9 m/s2 horizontal (4) 0.0 m/s2
(b) How long is the ball in the air? (c) What is the horizontal distance covered by the ball while in flight? (d) What velocity does the ball have at the top of its trajectory? 6. A golf ball was struck from the first tee at Lunar Golf and Country Club. It was given a velocity of 48 m/s at an angle of 40˚ to the horizontal. On the moon ...
