1. The problem statement, all variables and given/known data A ball of mass m = 8 kg is dropped from rest at a height h = 13.9 m above the ground. Ignore air resistance. (a)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? (b) If the ball is being thrown upwards instead with the same speed 4.9 m/s, what is the final speed when it hits the table? 2. Relevant equations Kf + Ugf = Ki + Ugi 3. The attempt at a solution vf = sqrt(v(initial)^2 + 2g(h - y)) I just plugged in numbers and got 16.8 for part (a) and I plugged in numbers for part (b) and got 17.3. Also, for part (b), I substituted y=0 because I chose the y-axis to start at the bottom where the hand would be.
