If this sounds ridiculously vague, I apologize - my physics teacher gave us this problem verbally and didn't want to clarify anything. 1. The problem statement, all variables and given/known data A ball is thrown at a 45 degree angle to the ground and remains in the air for 2.35 seconds by an individual standing 1.81m. How far did the ball travel? 2. Relevant equations I'm not really sure what equations would be suitable to use - I am unsure how I can calculate the initial horizontal speed of the ball. I know the horizontal and vertical components would be equal since it is a 45 degree angle but beyond this I am at a bit of a loss. I used vyf = vyo + gt to calculate that vyf was 23.03, however I am unsure how to factor in the individuals height to the equation.
