Question

An athelete set the record for the long jump with a jump of 8.90 m. Assume his initial speed on take off to be 9.5 ms^–1. How close did he come to the maximum possible range in the absence of air resistance? Take g = 9.78 ms^–2. 

Answer 1

Maximum Range

Thus, the difference is 9.23 m – 8.90 m = 0.33 m.
