Question

Which of the following statements regarding the kinematics of an elite sprinter competing in the 100 m sprint is correct?

The sprinter will reach their peak velocity around 50 - 60 m
The average acceleration over the first 50 m will be negative
The sprinters velocity will be negative as they cross the finish line.
The sprinter will only accelerate over the entire 100 m race

Answer 1

Option 1). The sprinter will reach their peak velocity around 50 - 60 m in a 100 m sprint.

Step-by-step explanation:

Among the given statements, the correct statement regarding the kinematics of an elite sprinter competing in the 100 m sprint is that the sprinter will reach their peak velocity around 50 - 60 m.

When a sprinter runs a 100 m race, they reach their peak velocity around the halfway point, which is approximately 50 - 60 m. After reaching this point, their velocity may start to decrease as they approach the finish line due to factors like fatigue and air resistance. Hence, Option 1) is the correct answer.
