Answer:

11m/s

Explanation:

Given parameters:

Mass of the lead shot = 8kg

Energy of the shot  = 484J

Unknown:

Velocity of the shot  = ?

Solution:

To solve this problem, we apply the kinetic energy formula;

        K.E  = [tex]\frac{1}{2}[/tex] m v²  

m is the mass

v is the unknown

 Now, insert the parameters and solve;

        484  = [tex]\frac{1}{2}[/tex] x 8 x v²

        484  = 4v²

           v² = 121

            v  = 11m/s
