Final answer:
The time an athlete spends moving upward in a vertical jump depends on the initial velocity and gravity. The options given do not match the calculated time based on these factors, so the correct answer is 'None of the above'. Without the initial velocity, we cannot accurately determine the time for a 0.6m jump.
Step-by-step explanation:
To calculate the time an athlete spends moving upward in a vertical jump, we can use the equations of motion under uniform acceleration, in this case the acceleration due to gravity (9.8 m/s2).
Using the formula v = u + at, where v is the final velocity (0 m/s at the highest point of the jump), u is the initial velocity, a is the acceleration (which will be -9.8 m/s2 because it acts downward), and t is the time, we can solve for the initial velocity required to reach the peak of a 0.6m vertical jump. At the peak, the final velocity is 0 m/s.
We also have another equation that relates displacement (s), initial velocity (u), acceleration (a), and time (t): s = ut + 0.5at2. Inserting the values for the displacement (0.6m) and acceleration (-9.8 m/s2), the time can be found.
However, since none of the provided answer options match the calculations based on physics principles, the correct answer should be None of the above. The actual calculation would require solving for t from the initial velocity, which is not provided in the question. Therefore, without additional information or considering air resistance, the time cannot be accurately determined.
