Question
Javelin is an Olympic sport where the athlete throws a wood stick a certain
horizontal distance, as shown in the image below.
Range
In this problem we are going to assume no air friction, and assume that the javelin
lands at the same height that it is launched from.
a) At what angle should a javelinier aim the javelin to hit the largest range
(farthest distance) possible? (You can just write down the number.)
b) The world's record is held by Jan Zelezny, at 98.48m. Using the angle from
part (a), what is the minimum speed at which Zelezny could throw his javelin
to reach that distance?
