Final answer:
On Planet Valaximia, if a ball is dropped 2m and takes 3 seconds to hit the ground, the acceleration due to gravity is approximately 0.44 m/s².
Step-by-step explanation:
The acceleration due to gravity on different planets varies. On Planet Valaximia, if a ball is dropped 2m and takes 3 seconds to hit the ground, we can calculate the acceleration due to gravity using the equation s = (1/2)gt^2, where s is the distance, g is the acceleration due to gravity, and t is the time. Plugging in the values, we get 2 = (1/2)g(3^2), which simplifies to 2 = 4.5g. Solving for g, we find g = 2/4.5 = 0.44 m/s². Therefore, the acceleration due to gravity on Planet Valaximia is approximately 0.44 m/s².
