1. The problem statement, all variables and given/known data A ball is thrown from the edge of a 10.0 m high cliff with a speed of 20.0 m/s at an angle of 30 degrees below horizontal. What is the speed of the ball when its hits the ground below the cliff? Options : 1) 26.3 m/s 2) 28.1 m/s 3) 31.4 m/s 4) 24.4 m/s 5) 29.5 m/s I am new to the forum so bare with me I don't know how the forum works. I have attempted a solution for the problem. I would appreciate if you could just tell me the equation to work with. 2. Relevant equations This is the equation I tried v = sqrt(2*g*h) 3. The attempt at a solution v = sqrt(2*9.8*10) v = 14 m/s The answer is not even in the options. Clearly I am doing something wrong actually way off. May be I am mixing wrong concept here. I would appreciate explanation with equation. Thank you.
