A ball is thrown horizontaly at 20m s from a 50 meter high cliff how long does it take the ball to reach the ground?
The horizontal component of the motion is irrelevant.
The ball starts with a vertical velocity of 0 metres per second and has an acceleration of 9.8 metres per second squared.
It travels 50 metres so s = 1/2*g*t^2
that is, 50 = 1/2*g*t^2
therefore t^2 = 10.2
and so t = 3.19 seconds.
What else can I help you with?
A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How high was the cliff rounded to the nearest meter?
Answer: 44 meters
A rock is thrown from a cliff and hits the ground 5 seconds later at a distance of 50 meters from the cliff How high was the cliff?
Assuming you throw the rock horizontally off the cliff it drops down at the acceletrtion of gravity. height= 1/2 gt^2 With g = 9.8 m/sec and t = 5 seconds we have height = (1/2) (9.8)(5)(5) = 122.5 meters notice it has nothing todo with the 50 meter distance, which depends on the horizontal velocity.
What is the recommended height of a meter socket from the ground?
the meter socket should be 1.8m from finished ground
What is the height of a rock that is thrown upward with an initial speed of 15 meter per second?
We have no idea how big the rock is, and no way to figure it out. But we can calculate that it reaches 11.48 meters above the ground before it starts falling.

What is the impact velocity of a rock thrown horizontaly from a cilff?
The impact velocity of a rock thrown horizontal from a cliff depends on two things, the initial speed of the rock (vi) and the height of the cliff (h). The final velocity (impact velocity) is represented by vfFor this formula, air resistance is neglected, and acceleration due to gravity is assumed to be 9.8 m/s2. The acceleration is positive here because down is being treated as the positive direction. You will get the same result if you use negative 9.8 m/s2 and make the height negative. sqr() means square root.vf = sqr(19.6h + vi2)For example if the rock was thrown off a 3 meter high cliff at 20 m/s, the impact velocity would be sqr(19.6 x 3 + 202), which would be sqr(58.8 + 202), which would be 21.42 m/s.The angle relative to the ground is the inverse tangent of sqr(19.6h)/viwhich in this case is tan-1( sqr(19.6 x 3)/20), which is tan-1(7.67/20) which is 21.0 degrees.

How long does it take for a ball to hit the ground if it was thrown vertically atop a 2 meter building at 15 meters per second vertically?
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!

Can you use ohm-meter to measure a resistance between the neutral line N and the ground E?
If the meter is sensitive enough and there is a resistance between the neutral and ground then the meter should be able to detect it.
How do you ground meter box?
To ground a meter box, usually a grounding electrode conductor is connected to a grounding electrode, such as a ground rod, buried in the earth near the meter box. This provides a path for excess electrical current to safely dissipate into the ground, preventing potential hazards. It is important to follow local electrical codes and regulations when grounding a meter box.
How do you ground a home gas meter?
To ground a home gas meter, you need to follow your local building codes and regulations. Typically, this involves connecting a copper wire from the gas meter to a grounding rod installed in the ground near the meter. It is important to hire a qualified electrician to ensure the grounding is done correctly and safely.
