Answer:
Given that
Initial velocity
u = 0
Tower height = total distance = 19.6m
g = 9.8 m/s2
Find out
Final velocity just before touching the ground.
Solution
Let us solve using third equation of motion
v2 = u2 + 2gs
v2 = 0 + 2 × 9.8 × 19.6
v2 = 384.16
v = √(384.16)
v = 19.6m/s
Answer
Final velocity just before touching the ground = v = 19.6m/s
Initial Velocity u=0
Fianl velocity v=?
Height, s=19.6m
By third equation of motion
v² = u²+ 2gs
v²= 0+2×9.8×19.6
v²= 384.16
