Help with this question.

Explanation:

The weight of some mass is defined as the product of mass by gravitational acceleration. In this way using the following formula we can find the weight.

where:

w = weight [N]

m = mass = 0.06 [kg]

g = gravity acceleration = 10 [N/kg]

Therefore:

By Hooke's law we know that the force in a spring can be calculated by means of the following expression.

where:

k = spring constant [N/m]

x = deformed distance = 6 [cm] = 0.06 [m]

We can find the spring constant.

Since we use the same spring on the moon and the same mass, the constant of the spring does not change, the same goes for the mass.

Since this force is equal to the weight, we can now determine the gravitational acceleration.

explanation:

v=uf/(u-f)
