You have just landed on Planet X. You take out a ball of mass 100 gg , release it from rest from a height of 16.0 mm and measure that it takes a time of 2.90 ss to reach the ground. You can ignore any force on the ball from the atmosphere of the planet. How much does the 100-g ball weigh on the surface of Planet X?

0.173 N.

Explanation:

We will calculate the mass and then use the following calculations on the surface of planet X that is :

We would use the following equation to get the value of g for planet X that is :

Then, put the values in the above equation.

Now, we will measure the ball weight on planet X's surface:

Then, we have to put the value in the above equation.

v=ir = 3x15 =45 v

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
