Answer:
4176 J
Explanation:
Ella speed (V) = 12 m/s, Mass = 58 kg.
Kinetic energy of a body is the energy it possesses as a result of its motion. It is the energy (work) needed to cause a given body to move from rest to its final velocity. It is measured in Joules. The kinetic energy of a body is the same until its velocity changes.
Kinetic energy = 1/2 × m × V²
Kinetic energy = 0.5 × 58 × 12² = 4176 J
