Homework Statement
A ball of mass m = 8 kg is dropped from rest at a height h = 13.9 m above the ground, as in Figure 7.4. Ignore air resistance.
If the ball is being released with a downward speed 4.9 m/s initially, what will be its final speed when it hits the table 0.7 m below the release point?
Homework Equations
Kf+Ugf=Ki+Ugi which is 1/2mvf2+mgy=1/2mvi2 +mgh
The Attempt at a Solution
I am confused in the wording of the question. What do they mean by "final speed when it hits the table 0.7m below the release point?"
