Correct Answer: Option n
Explanation:
V\(^2 = U^2 - 2gs\)
S = \(\frac{V^2 - U^2}{-2g} = \frac{O^2 - 30^2}{-2 \times 20}\) = 45m
Height from ground = 50 + 45 = 95m
Height from ground = 50 + 45 = 95m
V\(^2 = U^2 - 2gs\)
S = \(\frac{V^2 - U^2}{-2g} = \frac{O^2 - 30^2}{-2 \times 20}\) = 45m
Height from ground = 50 + 45 = 95m
Height from ground = 50 + 45 = 95m
