Final answer:
The initial velocity of the golf ball was 20.67 m/s.
Step-by-step explanation:
To find the initial velocity of the golf ball, we can use the horizontal distance it traveled and the time it took. We know that the golf ball traveled 62m horizontally and took 3.0s. The horizontal motion of the golf ball is not influenced by gravity, so we can use the following equation:
horizontal distance = initial velocity * time
Substituting the given values:
62m = initial velocity * 3.0s
Solving for the initial velocity:
initial velocity = 62m / 3.0s = 20.67 m/s
