Question

The rain drops falling from the sky neither hit us hard nor make
holes on the ground because they move with

(a) constant acceleration
(b) variable acceleration
(c) variable speed
(d) constant velocity

Answer 1

constant acceleration

Answer 2

Answer:

The correct answer is option (d) constant velocity.

Explanation:

Gravity does push things to decline with rising speed, but as they speed up air resistance increases. Eventually, the force of the air resistance exists sufficiently to balance the force of gravity, so the acceleration stops and the raindrop gets a constant terminal velocity. The terminal velocity of rain isn't high adequately to induce harm.

Since F = Ma so the force needed to stop the raindrop wouldn't be that largely because

• a raindrop doesn't contain a lot of mass
• Its speed (terminal velocity) isn't that high.

Therefore, the correct answer is option (d) constant velocity.
