As a raindrop falls from a cloud to the surface of earth,
a. its speed increases due to gravity.

i think it is a, may you me?

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
