Final answer:
Both high jump and javelin throw require athletes to generate considerable acceleration (option b) to achieve the necessary velocity for high performance in these events.
Step-by-step explanation:
In high jump and javelin throw, both events require the athlete to generate considerable acceleration. Acceleration is the rate of change of velocity of an object with respect to time and is crucial for athletes in these track and field events to achieve maximum distance or height.
For high jumpers, they need to accelerate quickly to achieve a high vertical velocity to clear the bar. Similarly, javelin throwers must accelerate the javelin to a high velocity for a successful and distant throw.
So, to answer the student's question, high jump is similar to javelin throw in that both events require the athlete to generate considerable acceleration.
