1. The problem statement, all variables and given/known data
In the shot put, a standard track-and-field event, a 7.30 kg object (the shot) is thrown by releasing it at approximately 40.0 degrees over a straight left leg. The world record for distance, set by Randy Barnes in 1990, is 23.11 m. Assuming that Barnes released the shot put at 40.0 degrees from a height of 2.00 m above the ground, with what speed, in m/s, did he release it?

2. Relevant equations

x-xo=vox*t

y=yo+voy*t+1/2*a*t^(2)

3. The attempt at a solution

Well I was a bit confused with the wording on this sentence:
In the shot put, a standard track-and-field event, a 7.30 kg object (the shot) is thrown by releasing it at approximately 40.0 degrees over a straight left leg.

It says 40 degrees over a straight left leg. What does that actually mean? Thanks!

I think 40 degrees over a straight left leg just means 40 degrees above the x-axis.
