This is false. There were many times in history when people discovered something that they didn't even know was possible or didn't even plan to discover it. Knowing tradeoffs doesn't mean that something won't surprise you or that all will go according to plan.
The answer is A. Astrology is pseudoscience because it is not scientifically backed.
(a) The vertical motion is accelerated by gravity. The horizontal component is constant (neglecting air resistance, if this is not a projectile motion, the horizontal component would also be accelerated)
(b) Vertical:

Horizontal:

(c) Use the kinematic equation for distance. Calculate only the vertical component (horizontal is irrelevant):

The ball will be in the air for about 3.9 s.
(d) The range is the horizontal distance traveled. We know the ball is in the air for 3.9s and it moves with a horizontal velocity of 23 m/s. So:

The range is 89.7 meters.
because of conduction the metal spoon is a conductor so the heat is getting traveled through the spoon and into your hand
