Answer
a. The object is in freefall so the magnitude of the acceleration is $g$.
b. The object is in freefall so the magnitude of the acceleration is $g$.
Work Step by Step
When an object is in freefall through the air, the magnitude of acceleration is always $g$ and the acceleration is directed straight down toward the ground. This acceleration comes from the force of gravity on the object and this force is always directed straight down toward the ground.
a. The object is in freefall so the magnitude of the acceleration is $g$.
b. The object is in freefall so the magnitude of the acceleration is $g$.
