Problem: You have just landed on Planet X. You take out a ball of mass 100g , release it from rest from a height of 15.5m and measure that it takes a time of 2.80s to reach the ground. You can ignore any force on the ball from the atmosphere of the planet.
Part A: How much does the ball weigh on the surface of Planet X?
I need help to find how much the ball weighs on the surface of Planet X.
