Answer:

Explanation:
Hello,
Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

Nevertheless, since we've got a angled force, it becomes:

In this case,
accounts for the formed angle, so the horizontal acceleration turns out into:

Best regads.
Acceleration is the rate at which an object changes its speed. When a raindrop is falling down from the clouds due to gravity, the veloicty is pretty much fast, however air resistance comes in action and slows the droplet down... it gives it a constant speed until it hits the ground
