Ram throws his ball ring from the roof of a 30.0-m-tall building at an angle of 30 degrees above the horizontal and with an initial speed of 30m/s. Ignore air resistance and calculate: 1. What is the initial horizontal velocity? m/s 2. What is the initial vertical velocity? m/s 3. What is the vertical velocity at the maximum height? m/s 4. The maximum height above the roof of the building that the ring reaches: (Write the answer in two decimal places and don't write the units, e.g. 0.20, 11.98. 125.30, 0.00)
