Select each example of a projectile 1. a skydiver 2. a baseball 3. running water from a faucet 4. a javelin thrown 5. a person jumping up and down 6. a clock falling out of a window select all that apply.

2. A baseball

4. A javelin thrown

Explanation:

In projectile motion all the objects will have two components of motion under gravity.

Horizontal component of motion must remains constant as there is no force in that direction while in vertical direction due to gravity the speed must change.

So whenever an object is projected at some angle with the horizontal which is less than 90 degree then in that case the motion must be projectile motion.

So here the correct options are

2. A baseball

4. A javelin thrown

0.19 m/s and 0.45 m/s

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
