Answer :
To find the time Usain Bolt takes to run the first 10 meters from the moment he starts moving, we need to subtract his reaction time from the total time it took for him to complete the first 10 meters.
1. Total time for the first 10 meters: According to the table, Usain Bolt's total time for the first 10 meters is 1.89 seconds.
2. Reaction time: The reaction time given is 0.146 seconds, which is the time taken before he actually starts moving.
3. Actual running time for the first 10 meters: We subtract his reaction time from the total time.
[tex]\[ \text{Running time for the first 10 meters} = \text{Total time for the first 10 meters} - \text{Reaction time} \][/tex]
Substituting the values:
[tex]\[ \text{Running time for the first 10 meters} = 1.89 \, \text{seconds} - 0.146 \, \text{seconds} \][/tex]
[tex]\[ \text{Running time for the first 10 meters} = 1.744 \, \text{seconds} \][/tex]
Therefore, Usain Bolt takes 1.744 seconds to run the first 10 meters from the moment he starts moving.
