Hi there!

a = -9.81 m/s²

When throwing a ball into the air (ignoring air resistance), the acceleration in the vertical direction is ALWAYS constant and equal to the acceleration due to gravity.

In this instance, the acceleration due to gravity is downward, resulting in the object falling. So, we must put a negative sign:

Thus, a = -9.81 m/s².
