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

A golf ball is hit at an angle of 30 degrees, it travels 50m landing straight in the hole. Ignoring air friction, what is the initial velocity?

**2. Relevant equations**

not too sure, d=vi.t+1/2.a.ts∧2, vf=u∧2+2.a.d, v=u+a.t, d=u.t

**3. The attempt at a solution**

Vertical initial Velocity= usin30

Horizontal initial velocity= ucos30
