Answer to a math question A ball is launched from the ground vertically into the air with a speed of 10 m/s. Calculate the speed of the ball the moment it returns to the ground.
1. Initial speed of the ball, u = 10 \, \text{m/s}.
2. Using the conservation of energy and the symmetry of projectile motion, the ball will have the same speed when it returns to the ground.
3. Therefore, the final speed v = u = 10 \, \text{m/s}.
Answer: v = 10 \, \text{m/s}.
