Answer:
Now you know gravity is a major force in the universe. It keeps us from floating away, controls the ocean's tides, guides plant growth, keeps Earth and other planets in orbit.
Explanation:
Answer :Force is exerted by the Earth on the rock is 280 N .
Given :
Mass of rock falling falling , m = 28 kg .
Acceleration due to gravity ,
.
We need to find the force exerted by the earth on the rock .
Let force exerted be F .
Now , we know by Newton's Law Of Motion .
F = ma .......( 1 )
Here , m is mass and a is acceleration in this case it is
.
Putting all these value in equation( 1 ) we get ,

Therefore, this is the required solution .
