Question

A ball is projected horiontally with a velocity of $5m/s$ from the top of a building $19.6m$ high. The horizontal distance covered by ball take to hit the ground?

• A. $20m$
• B. $5m$
• C. $25m$
• D. $10m$

Answer 1

The correct option is D $10m$

Time taken$:$ $T=\sqrt{\frac{2\times 19.6}{9.8}}=2sec$

$R=S\times T=5\times 2=10m$

Hence,

option $\left(D\right)$ is correct answer.
