Both rocks hit the ground at the same time and at the same distance from the base of the cliff. Option A is correct.
<h3>What is speed ?</h3>
Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its SI unit is m/sec.
If the resistance is ignored, things falling near the Earth's surface have the same estimated acceleration due to gravity of 9.8 meters per second.
As a result, the objects' acceleration is the same, and their velocity is growing at a consistent pace.
So that both rocks hit the ground at the same time and at the same distance from the base of the cliff.
Hence, option A is correct.

The kinetic energy of a moving object is calculated through the equation,
KE = 0.5mv²
where m is the mass and v is the velocity.
Substituting the known values,
KE = 0.5(620 kg)(9 m/s)²
KE = 25,110 J
Thus, the kinetic energy is equal to 25,110 J.
Answer:increasing any of them, either mass or speed by 1unit will cause an increase in energy,
Explanation:
By increasing any of them, either mass or speed will cause an increase in energy.
Because kinetic energy is proportional to mass and also directly proportional to velocity
Answer:
They both experienced the same force as they weigh the same amount
Newtonian physics
Explanation:
Answer:
D
Explanation:
We must never use a piece of pipe as a leverage extension on the handle on a wrench.
Hence option d is correct.
