Question
You are on a cliff of height h, and you throw three identical balls with an initial speed. One ball is thrown vertically upward, one ball is thrown vertically downward, and one ball is thrown horizontally. All three eventually hit the ground near the base of the cliff (which is horizontal). Neglecting air friction, which ball hits the ground with the highest speed?
The ball thrown horizontally
The ball thrown upward
All three balls hit the ground with the same speed.
The ball thrown downward
1.The ball thrown horizontally
2.The ball thrown upward
3.All three balls hit the ground with the same speed.
4.The ball thrown downward
Explanation / Answer
here
max height V^2 - u^2 = 2 gh
so Hmax is = V^2/2g
max velcoity = 2gh
so here answer is option 2, The ball thrown upward
