Homework Statement
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.
Homework Equations
This is the equation I tried
v = sqrt(2*g*h)
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.
