**[SOLVED] Pressure on a ball**

**1. Homework Statement**

Suppose you release a small ball from rest at a depth h below the surface of water. The ball shoots upwards above the surface by 1m. If the density of the ball is .400 that of water and drag force on the ball from water is negligible, at what depth was the ball released?

**2. Homework Equations**

I'm assuming p(2)=p(1) + dg(y(1)-y(2))

**3. The Attempt at a Solution**

I think I have to find the pressure on the ball in order to start solving this. I also know that the force due to gravity on the ball is less than that of the buoyancy force because the ball shoots upwards. I also know that the pressure increases as h below the water increases
