1. In this problem, the target is at the origin when the projectile is launched. The target has a constant velocity of 25 m/s to the right. If the projectile is launched horizontally, what must its initial speed be in order to hit the target? Explain your answer and then test it.
2. If the height of the cliff is 50% greater, what will the initial speed have to be in order to hit the moving target? Explain your prediction and then test it.
3. If the projectile is launched on the Moon, what will the initial speed have to be? Again, explain and test.
4. Suppose now that the projectile is launched at a 60° angle on the Earth. What will the initial speed of the projectile have to be in order to hit the target? Explain and test.
