Distance = 1/2×10×4×4=80m
Half = 40m
40=1/2×10×t²
t²=40×2/10=8
t=(8)½ = 2×root2
Half = 40m
40=1/2×10×t²
t²=40×2/10=8
t=(8)½ = 2×root2

Answer:
The correct answer of this question is 80m
Explanation:
Given - A height of Tower hits the ground after 4 seconds.
To find - How much time does it take to cover the first half of the distance from the tip of the tower.
Distance = 1/2 × 10 × 4 × 4 = 80m
Half = 40m
40 = 1/2×10×t²
t²= 40×2/10 = 8
t = (8)½ = 2 × root2
The first half of the distance 80m
