The next few questions challenge you to figure out the
acceleration due to gravity ( g ) on various hypothetical alien
planets. On Planet #1, you drop a stone from rest, 73.3 m above the
ground, and the stone hits the ground 6.20 s later. What is the
value of g on Planet #1?
On planet #2, you launch a projectile straight up from the
ground at a speed of 21.9 m/s. The projectile reaches a maximum
height of 75.2 m before falling back to the ground. What is the
value of g for planet #2?
On planet #3, you fire a projectile horizontally from the edge
of a vertical cliff 76.5 m above the ground, with an initial speed
of 56.3 m/s. The projectile lands 74.5 m away from the base of the
cliff. What is the value of g for planet #3?
On planet #4, you fire a projectile from the ground at an
initial speed of 53.1 m/s at an angle of 37.3 degrees above the
horizontal. The projectile lands 20.0 m away from the launch point.
What is the value of g for planet #4?
On planet #5, a stone dropped from a height of 43.4 m above the
ground will hit the ground at a speed of 69.4 m/s. What is the
value of g for planet #5?
