Question
At the 2004 Olympic Games in Athens, Dwight
Phillips won the gold medal in men’s long
jump with a jump of 8.59 m. If the angle of
his jump was 23°, what was his takeoff speed?
(Treat the jumper as an object; ignore that his
legs are in front of him when he lands.)

L=vₒ²•sin2α/g,
vₒ =sqrt{Lg/ sin2α}=
=sqrt{8.59•9.8/sin46º}=
=10.8 m/s
vₒ =sqrt{Lg/ sin2α}=
=sqrt{8.59•9.8/sin46º}=
=10.8 m/s

Elena that equation you wrote makes no sense at all......
