A projectile is launched straight up at 51.5 m/s from a height of 88.5 m, at the edge of a sheer cliff. The projectile falls, just missing the cliff and hitting the ground below.
1. Discover the maximum height of the projectile above the point of firing.
2. Discover the time it takes to hit the ground at the base of the cliff.
Your response differs from the correct answer by more than 100%. s
3. Discover its velocity at impact.
Is the velocity up or down at impact? Is that direction positive or negative?
