1. The problem statement, all variables and given/known data A handball is projected at an angle of 30 degrees with the horizontal from a 20 meter tower with an initial vertical velocity of 10 ms and an initial horizontal velocity of 20 ms. Find the total time of flight. 2. Relevant equations 3. The attempt at a solution I know that 0=Vi + at will give me time up X2 will give total time for a projectile with same landing height, but what do I need to use if it has a different landing height?
