A stone is thrown straight down from the top of a cliff with an initial speed of 6m/s it reaches the bottom in 3s how high is the cliff
To find the height of the cliff, we can use the formula:
h = 1/2 * g * t^2
where:
h = height of the cliff
g = acceleration due to gravity (9.8 m/s^2)
t = time taken for the stone to reach the bottom (3s)
Plugging in the values:
h = 0.5 * 9.8 * (3)^2
h = 0.5 * 9.8 * 9
h = 44.1 meters
Therefore, the height of the cliff is 44.1 meters.
