need HELP!!

which of the following exhibits parabolic motion

a. stone thrown into a lake
b. space shuttle orbiting Earth
c. leaf falling from a tree
d. train moving along a flat track

which of the following does NOT exhibits parabolic motion

a. frog jumpping from land into water
b. basketball thrown to a hoop
c. flat piece of paper released from a window
d. baseball thrown to home plate

please help me :)

a, c

Think that out, and why.

Of the options given, the objects that exhibit parabolic motion are:

a. A stone thrown into a lake.
c. A leaf falling from a tree.

To determine whether an object exhibits parabolic motion, you can consider if it follows a curved path resembling a parabola. In the case of a stone thrown into a lake, it follows a parabolic trajectory due to the combination of an initial upward force and the force of gravity pulling it downward. Similarly, a leaf falling from a tree also follows a curved path due to the force of gravity.

On the other hand, the objects that do not exhibit parabolic motion are:

a. A frog jumping from land into water.
b. A basketball thrown to a hoop.
c. A flat piece of paper released from a window.
d. A baseball thrown to home plate.

While these objects experience some form of motion, they do not follow a parabolic path because factors such as air resistance, external forces, or specific motions of the object cause their trajectories to deviate from a smooth curve.

It's important to consider factors such as initial velocity, gravitational force, and other external forces to determine the type of motion an object exhibits.
