Question

Missy Diwater, the former platform diver for the ringling brothers circus had a kinetic energy of 15,000 joules just prior to hitting the bucket of water. If missy's mass is 50kg, the what was her velocity.

Answer 1

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

Answer 2

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
