Answer :
The kinetic energy of Karine Dubouchet of France is 99600, her mass was 51kg. So, her speed at that time will be 62.49m/s.
What is Kinetic energy?
Kinetic energy is the energy which is present in the body of an object which is under motion. This energy is converted into potential energy when the object comes at rest. The SI unit of Kinetic energy is Joules (J). It is directly proportional to the mass and velocity of the object.
KE = 1/2 × m × v²
where, KE = Kinetic energy of the body,
m = mass of the body,
v = velocity of the body
Here, the Kinetic Energy is 99600 Joules and mass is 51 kg. Therefore, the speed or velocity of the object can be calculated as:
KE = 1/2 × m × v²
2KE/m = v²
√2KE/m = v
√2×99600/51 = v
√199,200/51 = v
√3,905.9 = v
v = 62.49m/s
Therefore, the speed or velocity of Karine Dubouchet is 62.49m/s.
