Margaret Schwartz · Answer 1

Kinetic energy=0.5*mass * (velocity^2)

15,000 J=0.5*50*v^2

15,000J=25v^2

600 J=v^2

Velocity = 24.49 ms^-1

Macey Jimenez · Answer 2

Answer: 24.49 m/s

Explanation:

Kinetic energy = ½ mass * (velocity) ²

K. E = 15,000J

Mass (M) = 50Kg

Velocity (v) = ?

15000 = ½ * 50 * v²

V² = [ (2 * 15000) / 50]

V² = 600

Take the square root of both sides

V = 24. 49 m/s
