Answer:
7267.19 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 96.54 kg
Velocity (v) = 12.27 m/s
Kinetic energy (KE) =?
Kinetic energy is simply defined as the the energy possess by a body in motion. Mathematically, it can be expressed as:
KE = ½mv²
Where
KE => is the kinetic energy
m => is the mass of the object
V => is the velocity of the object.
With the above formula, we can obtain the kinetic energy Usain Bolt as follow:
Mass (m) = 96.54 kg
Velocity (v) = 12.27 m/s
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 96.54 × 12.27²
KE = 48.27 × 150.5529
KE = 7267.19 J
Thus, the kinetic energy of Usain Bolt is 7267.19 J
