Question.

An object has a weight of 5.10 newtons (N) at the level of the sea, where the acceleration due to gravity is 9.81 m/s^2.

What is the acceleration caused by gravity on the object if it is placed in a spaceship to 1,000 km above the sea level, where the gravity exerts a force of 3.81 N on the object?

Solution.

F=m*a So, let’s calculate a mass of the object.

Now, we could calculate acceleration where the gravity exerts a force of 3.81 N on the object.

m=F/a=5.10/9.81=0.52 kg

a=F/m=3.81/0.52=7.33 m/s^2
