Question

ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements. An object on earth has a mass of 4 kg. Calculate its weight on another planet that has an acceleration due to gravity one-half that of the earth. w2 = N

Answer 1

19.6 kg*m/s^2 = 19.6 N

Step-by-step explanation:

Weight is mass times acceleration due to gravity. And hopefully you know that acceleration due to gravity on earth is 9.8 m/s^2 So what is half of that? 4.9. So now the calculation is super simple.

mass = 4 kg and acceleration = 4.9 m/s^2 so now we multiply these two numbers and get 19.6 kg*m/s^2. kg*m/s^2 is also known as Newtons, abbreviated with an N so the final result is 19.6 N.
