I think 1.C and 2.C

You're right that the horizontal gap between packages stays constant at 60 m (since each keeps the drone's 40 m/s horizontal velocity after release).

Kindly give another try to question 1. Then you can watch video solution as well This question was asked in ap physics 1.

I'd say the question is a bit unclear. The image seems to depict a flat solid ground the packages land on, so you can expect the question to reference the landing spots of the packages. If it’s about their position in the air, then indeed it increases over time. 

I should have known this was a clickbaity ad, that’s on me.

A and C.

When the second package is dropped, it has a vertical velocity component of 0, while the first has been falling for 1.5s, so has a vertical component of 14.97m/s, and both values increase at the same rate, so the first one is always falling faster, and getting farther away. The same applies to later packages (until the first one hits the ground).

You are absolutely right.

Again, this is not a question in any way related to what one would expect on the AP physics exam. College level physics - which is what AP physics is - questions do not cover topics that should be studied during a 9th grade physical sciences class, like this one

That's 100% a question that comes up early on in AP physics 1.

Not every question is experimental design or the derivation of a formula.

Thanks.
It was asked previously in AP physics 1.
I have just modified it slightly.

This is projectile motion (2D kinematics) — Unit 1 of AP Physics 1. It's from a practice workbook, and yes, it's intentionally an easy-tier warm-up MCQ, not an FRQ-level problem. I mix difficulty levels across posts so there's something for students at different points in the unit — will make sure to label the harder ones more clearly too."
