True.
When a projectile is launched upward, it decelerates due to the force of gravity until it reaches its peak height, at which point its speed is zero. As it falls back down, it accelerates due to gravity. However, if we consider the scenario where the projectile is launched and then returns to the ground, it will have the same speed upon returning to the ground (ignoring air resistance) as it had when it was launched, assuming it was launched vertically.
If the projectile hits the ground with less speed than it had when projected upward, it suggests that some energy was lost (for example, due to air resistance or other factors). In an ideal scenario without air resistance, the statement would be false, but in a real-world scenario where air resistance is present, the statement can be true.
So, the answer can be context-dependent, but generally, in a real-world context, the statement can be considered True.
