The current (as ofsummer 2023) world record forthe men's 100-meter run is held by Jamaica's Usain Bolt, with a time of 9.58 seconds. Bolt set the record on August 16, 2009, at the IAAF World Championships in Berlin. This time can be broken down as follows: o a reaction time of 0.15 5, while Bolt remained at the start line; 0 a time of 2.74 s running from the start to the 20meter mark; 0 a time of 1.75 5 running from the 20meter mark to the 40meter mark; 0 a time of 1.67 5 running from the 40meter mark to the 60meter mark; 0 a time of 1.61 5 running from the 60meter mark to the 80meter mark; 0 a time of 1.66 s running from the 80meter mark to the 100meter mark (the finish line).

Based on that, what was Bolt's acceleration (which we will assume to be constant), during the first 10 meters of the race? Do not include the reaction time period, while he was at rest, and note that the 2.74 s time period for the first 20 meters starts after the reaction time period ends. m/s2 Type your numeric answer and submit 18.1 X You are incorrect
