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
