SUMMARY
The discussion centers on calculating the required speed for a basketball to reach a hoop located 2.8 meters away and 0.4 meters high, thrown at a 60° angle. The correct approach involves using the equations of motion, specifically V=V0+at and r(t)=r0+v0t+0.5a^2, while ensuring proper dimensional analysis. A common mistake identified was the incorrect substitution of terms, specifically using (5.6 V_0)^2 instead of the correct ({5.6/V_0})^2. Following the advice to work with symbols before substituting values led to the correct answer.
