Knowing that when you throw something in the air, the speed will be 0m/s.
The acceleration due to gravity is 9.8m/s^2.
v2=0
v1=24
a=9.8
The formula is:
v2=v1+a(t)
v2-v1/a=t
0-24/9.8
24m/s/9.8m/s^2=t (You can choose which direction is positive and negative)
2.45s=t
t=2.45*2s (Since you calculate both going up and down)
t=4.9s

The answer to your question is AB is 50 kilometers.
50 kilometers
The answer is 509 m.
Let point B be 253 m from point A. Let point C be 64 s away from point B.
Let d1 be the displacements from point A to point B and d2 and be the displacements from point B to point C
Step 1. Calculate the displacement from the point B after 64 s.
Step 2. Calculate the displacement from the point A by summing up two distances (d1 and d2).
Step 1.
v = d2/t
v = 4 m/s
d2 = ?
t = 64s
____
4 = d2/64
d2 = 64 * 4 = 256 m
Step 2:
d = d1 + d2
d1 = 253 m
d2 = 256 m
d = 253 + 256 = 509m
