Question

Assuming no air resistance, all projectiles have:

Answer 1

The same drop time, without the air, all objects fall at the same time. Even a feather and bowling ball

So all objects fall at the same time

Answer 2

Step-by-step explanation:

When there is no resistance, then the acceleration of all the projectiles is in the vertically downwards direction which is equal to the acceleration due to gravity.

So, the net acceleration of all the projectiles is always same which is equal to acceleration due to gravity.
