Explanation:

Given that,

The relationship between the time of flight and horizontal range is given by:

R=5T^2.....(1)

The range of projectile is given by :

R=\dfrac{v^2\ sin2\theta}{g}

The time of flight is given by :

T=\dfrac{2v\ sin\theta}{g}

\dfrac{v^2\ sin2\theta}{g}=5\times (\dfrac{2v\ sin\theta}{g})^2

sin2\theta=\dfrac{20\ sin^2\theta}{g}

On solving above equations :

tan\theta=\dfrac{g}{10}

Since, g=10\ m/s^2

\theta=45^{\circ}

So, the angle with which the ball is thrown is 45 degree celcius. Hence, this is the required solution.
