Answer:
The height of the cliff is 90.60 meters.
Explanation:
It is given that,
Initial horizontal speed of the stone, u = 10 m/s
Initial vertical speed of the stone, u' = 0 (as there is no motion in vertical direction)
The time taken by the stone from the top of the cliff to the bottom to be 4.3 s, t = 4.3 s
Let h is the height of the cliff. Using the second equation of motion in vertical direction to find it. It is given by :
h = 90.60 meters
So, the height of the cliff is 90.60 meters. Hence, this is the required solution.
Answer:
<h3>The answer is 36,400 kgm/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 1,300 kg
speed / velocity = 28 m/s
We have
momentum = 1,300 × 28
We have the final answer as
<h3>36,400 kgm/s</h3>
Hope this helps you
Similar properties. Cause they have the same number of valence electrons
We can find for the country by using a map with angle coordinates.
