Physics: An angry soccer player uses dynamite to blow the rival teams stadium apart after a close loss. Debris from the explosion flies off in all directions and is later found at distances as far as 50 m from the explosion. Estimate the maximum speed at which debris was blown outward by the explosion.

The maximum speed is $u = 22 \ m/s$

Explanation:

From the question we are told that

The distance covered by the debris is $R = 50 \ m$

The maximum range of the debris projectile is mathematically represented as

$R = \frac{ u^2 sin^2 \theta }{g}$

At maximum $\theta = 90 ^o$

Now making u which is the maximum speed at which debris was blown outward by the explosion.

we have

$u = \sqrt{\frac{R * g }{ sin ^2 \theta } }$

substituting values

$u = \sqrt{\frac{50 * 9.8 }{ [sin 90] ^2} }$

$u = 22 \ m/s$
