Question
As Usain Bolt began his world record-breaking 100 m sprint in 2009, the net force on his 94 kg body was 893 N.
Solution
Sure, I can help with that. The question seems to be asking for an analysis of Usain Bolt's sprint using the principles of physics.
Given: Mass (m) = 94 kg Net force (F) = 893 N
We can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The law is usually written as F = ma, where F is the net force, m is the mass of the object, and a is its acceleration.
We can rearrange the formula to solve for acceleration (a):
a = F/m
Substituting the given values:
a = 893 N / 94 kg = 9.5 m/s²
So, the acceleration of Usain Bolt at the beginning of his sprint was 9.5 m/s².
