Furkat [3]

We don't know that at all. The 3rd law says that the REaction is opposite and EQUAL to the action.  We don't know where that "twice as much" comes from.

Thought Experiment: A monkey escapes from a zoo and climbs a tree. After failing to entice the monkey down, a zookeeper fires a
Andreyy89

Explanation:

When bullet is shot towards the monkey then let say the distance of monkey from the bullet is "d"

so we can find the time to reach the bullet to the monkey

t = \frac{d}{vcos\theta}

Now similarly we can find the vertical displacement of the bullet in the same time

\Delta y = vsin\theta t - \frac{1}{2}gt^2

\Delta y = v sin\theta (\frac{d}{vcos\theta}) - \frac{1}{2}gt^2

so it is given as

\Delta y = d tan\theta - \frac{1}{2}gt^2

here if the monkey is initially at height H above the ground at given angle then we can say

H = dtan\theta

so we can say that

\Delta y = H - \frac{1}{2}gt^2

So if at the same time monkey will fall down then the height of monkey from ground after time "t" is given as

\Delta y = H - \frac{1}{2}gt^2

so here bullet will hit the monkey as both monkey and bullet are at same position.
