Here we see that maximum height H of all trajectories are same,
H = [Vvertical]^2/2g
Vvertical is same. for all,
time of flight = 2*Vvertical /g = same for all

Three objects move and their velocity vs time graphs are shown
below
The following questions refer to the velocity vs time graphs
above.
1.Are any of the graphs shown representing objects that are
slowing down?
2.Do any of the objects have a negative acceleration? How can
you tell?
3.Which object’s motion(s) most likely is/are experiencing air
resistance? Explain your reasoning.
4.Sketch what the acceleration vs time graphs would look like
for each of the velocity graphs.
