Answer:

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

How is work defined in physics
Tcecarenko [31]

Explanation:

Work is the dot product of the force and displacement vectors.

W = F · d

In other words, it is the force times the parallel component of the distance.

W = F d cos θ, where θ is the angle between the force and distance.
