The speed of the ball when it returns to the same horizontal level is 8 m/s.
The given parameters;
- initial speed of the ball, u = 8 m/s
- angle of projection, θ = 35⁰
During the motion of a projectile, the speed of the projectile reduces as the projectile moves upwards and eventually becomes zero at the maximum height.
As the projectile moves downwards, the speed of the projectile starts to increase and it will become maximum (equal to the initial speed) before the projectile hits the ground.
Thus, we can conclude that the speed of the ball when it returns to the same horizontal level is 8 m/s.
