While standing at the edge of a cliff, you throw a stone upward with an initial speed of 6.79 m/s. the stone subsequently falls to the ground, which 12.1 m below the point where the stone leaves your hand. at what speed does the stone impact the ground? ignore air resistance and take g= 9.81 m/s^2 a) 13.6 m/s
b) 14.5 m/s
c) 15.3 m/s
d) 16.8 m/s

d) 16.8 m/s

Explanation:

In this situation we are dealing with paarabolic motion with a constant acceleration (acceleration due gravity), hence, the following equation will be useful to find the

Where:

Is the final velocity of the stone

Is the initial velocity of the stone

is the constant acceleration of the stone due gravity

is the height of the cliff

This is the final velocity of the stone

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

answer; how far out of place which the object finished relative to the starting location;
