A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 40 km/h at the 53-m mark. He then maintains this speed for the next 79 meters before uniformly slowing to a final speed of 33 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur? Finish line 39.9 m Correct Calculate (a) the magnitude of the tangential acceleration near start of the race and (b) the magnitude of the tangential acceleration near the end of the race. Answers: (a) latl= 11647 m/s² (6) loel = 0.2897 m/s² Hint Attempts: unlimited Using multiple attempts will impact your score. 10% score reduction after attempt 5 Part 2 Part 1

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
