 An athlete participates in a discus throw competition during an Olympiad that takes place in a city where acceleration due to gravity is 9.80 m/s2. He throws the discus with an initial velocity of 20.0 m/s at an angle of 30.0 above the horizontal. Neglecting the height of the discus at the point of release, what is the range of the discus?

u=iniatial velocity

v=final velocity

u= vcos theta-at

0=20cos30-9.8t

17.32=9.8t

t=1.767

range=ut=20*1.767

=35.35 m

17.32=9.8t did you divided or did you multiplied?
