Two rocks, a and b, are thrown horizontally from the top of a cliff. rock a has an initial speed of 10 meters per second and rock b has an initial speed of 20 meters per second. how would you describe the time it takes for the rocks to reach the ground and the horizontal distance they travel? both rocks hit the ground at the same time and at the same distance from the base of the cliff. both rocks hit the ground at the same time, but rock b lands twice as far as rock a from the base of the cliff. both rocks hit the ground at the same time, but rock a lands twice as far as rock b from the base of the cliff. rock b hits the ground before rock a, and rock b lands twice as far as rock a from the base of the cliff.

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.
