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

find time to reach max height

max height is 0.870m

mass of diver is 70kg

makes an angle when diving of 85 degrees

**2. Relevant equations**

Vf=Vi + gt

**3. The attempt at a solution**

Vi=0

Vf=gt

t=vf/g

= 0.870/9.8

not sure if this the right approach
