# Projectile motion problem

**1. The problem statement, all variables and given/known data**

**2. Relevant equations**

R = 1/2 gt^2

R+x = vt

**3. The attempt at a solution**

For a), I tried to find t first, which is equal to √(2R/g). Then, I put t = √(2R/g) into the equation R+x = vt, and I found out that v = (R+x)/√(2R/g), is that correct?

For b), is the answer (R+x)?
