Broader sense of "Free Fall" - under he sole influence
of gravity
Even an object thrown UPWARD can be called "Free
Fall" in the broader sense.
In the entire motion (including going upward, at the
highest point and then falling downward), the
acceleration due to gravity has the same magnitude
and the same direction.
In (Figure 2)a stone is thrown upward with an initial velocity $v_0 = 7.2 \text{ m/s}$ from a height of $H_0 = 8.8 \text{ m}$ above the ground. The
magnitude of the gravitational acceleration is $9.8 \text{m/s}^2$. Take UPWARD as positive direction,
Part E - Figure 2 Case 2: What is the maximum height above the ground? Keep 2 digits after the decimal point.
Figure 2 max height above ground = 11.44 m
