Question

Need help with part d and e. Preferably as soon as possible 

At the Olympics, a discobolus “discus thrower" starting from rest, spins up to an angular
velocity of 20 rad/s in 0.7 s. (Assume perfectly circular motion)
(a) What is the angular acceleration during this spin up?
nce released, the discus flies off with a tangential velocity of 18 m/s at an angle 30° above
e horizontal.
(b) What is the approximate length of the discus players arm (from the center of the
discus player to the point where he held the discus in his hand)?
(c) How high does the discus go above the initial release point?
he discus lands 1.95s after the release.
(d) What height was the discus released from?
(e) How far from the discus player does it land?
