Solution
- The equation of the path is:
- When the projectile hits the ground, the height of the projectile, i.e. h(t) = 0.
- We are told that the time when the projectile is on the ground is 5 seconds.
- Thus, when t = 5, h(t) = 0.
- We can use this information to solve the question as follows:
Final Answer
The answer is 7.5 meters
