1) On Planet #1, you drop a stone from rest, 94.9 m above the ground, and the stone hits the ground 2.96 s later. What is the value of g on Planet #1?

2)On planet #2, you launch a projectile straight up from the ground at a speed of 32.6 m/s. The projectile reaches a maximum height of 68.0 m before falling back to the ground. What is the value of g for planet #2?

3)On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 62.4 m above the ground, with an initial speed of 78.6 m/s. The projectile lands 28.4 m away from the base of the cliff. What is the value of g for planet #3?

4)On planet #4, you fire a projectile from the ground at an initial speed of 29.4 m/s at an angle of 30.3 degrees above the horizontal. The projectile lands 36.5 m away from the launch point. What is the value of g for planet #4?
