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 speedv = u = 10 \, \text{m/s}
Answer:v = 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
