At a track-and-field meet, the best long jump is measured as 8.00 m. The jumper took off at an angle of 46° to the horizontal.
(a) What was the jumper’s initial speed? (Neglect air resistance.)
1 m/s
(b) If there were another meet on the Moon and the same jumper could attain only half of the initial speed he had on the Earth, what would be the maximum jump there?
2 m
(Air resistance does not have to be neglected in part (b). Why?)
