Question

If time of flight of projectile is 2sec then it cover range in??

Answer 1

$\Large\underline{\underline{\mathfrak Given:}}$

• Time of flight (T) = 2 sec

$\Large\underline{\underline{\mathfrak To\:Find:}}$

• Range (R)

$\Large\underline{\underline{\mathfrak Formula\:Used:}}$

$\large{\boxed{\boxed{\sf \pink{T=\dfrac{2u}{g}}}}}$

$\large{\boxed{\boxed{\sf \pink{R=uT}}}}$

$\Large\underline{\underline{\mathfrak Solution:}}$

$\Large{\sf T=\dfrac{2u}{g} }$

$\implies{\sf 2=\dfrac{2×u}{10}}$

$\implies{\sf u=\dfrac{2×10}{2} }$

$\implies{\sf u=10\:m/s }$

$\Large{\sf R=uT}$

$\implies{\sf R=10×2 }$

$\implies{\sf \red{R=20\:m}}$

$\Large\underline{\underline{\mathfrak Answer:}}$

⛬ Range covered is 20 m
