Question

A football is kicked at an angle of 37° with a velocity of 20m/s the ball lea the s at ground level . Find the maximum height

Answer 1

Given :

• Football is kicked at an angle (∅)=37°
• With Velocity (u) = 20m/s

To Find :

• Maximum Height (Hmax)

Formula Used :

$\bullet\underline{\boxed{\sf H_{max}=\dfrac{u^2sin^2\theta}{2g}}}$

g = Acceleration due to gravity = 10m/s²

Solution :

$\implies{\sf \dfrac{(20)^2sin^2 37}{2 \times 10} }$

sin37 = 3/5

$\implies{\sf \dfrac{400\times 3 \times 3}{2 \times 10 \times 5 \times 5}}$

$\implies{\sf \dfrac{36}{5}}$

$\implies{\bf H_{max}= 7.2 \: m}$

Answer :

Maximum Height of ball is 7.2m
