A golf ball mass of 4.7 x 10-2 kg is hit by Tiger Woods and drops exactly into a hole 100 meters away. It is observed that the angle between the initial velocity vector and the horizontal plane is 30 degrees. What is the magnitude of the initial velocity? Isn't the problem missing additional information? Like time to traverse the 100 meters in the x-direction or the maximum height it reaches?? I don't see how I can solve this problem with additional information.
