Final answer:
Usain Bolt's kinetic energy with a mass of 94 kg and a speed of 12.4 m/s is calculated using the kinetic energy formula, resulting in 7294.4 joules.
Explanation:
The student has asked what was Usain Bolt's kinetic energy (KE) when his mass is 94 kg and his velocity is 12.4 m/s. To find Bolt's KE, we can use the kinetic energy formula KE = 0.5 * m * v^2, where m is mass and v is velocity. Plugging the values into the formula gives us KE = 0.5 * 94 kg * (12.4 m/s)^2. This calculation gives us a kinetic energy of 7294.4 joules.
Answer:The fastest recorded human footspeed was recorded between 60 and 80m in Bolt's world record 9.58-second 100m final in Berlin in 2009. Bolt was clocked at 44.72km/h, which is 27.8mph. The Jamaican covered the distance between 60-80m in a time of just 1.61 seconds
