Part A

Which statement about the frog's motion is correct?

On the way up its acceleration is $9\mathrm{.}8\frac{m}{s^2}$ upward, and on the way down its acceleration is $9\mathrm{.}8\frac{m}{s^2}$ downward.

On the way up and on the way down its acceleration is $9\mathrm{.}8\frac{m}{s^2}$ downward, and at the highest point its acceleration is zero.

On the way up$,$ on the way down, and at the highest point its acceleration is $9\mathrm{.}8\frac{m}{s^2}$ downward

At the highest point, it reverses the direction of its acceleration.
