The weight of a rock on the moon is 0.85 N. If acceleration due to gravity on the moon is 1.7 m/s2, what will be its weight on the earth
weight = mg, so, if g doubles, so does weight.
so, weight on earth is .85 * (9.8/1.7) = 4.9 N
how boring. surely they didn't have to make the values come out so normal.
To find the weight of the rock on Earth, we first need to understand the concept of weight and how it is affected by gravitational acceleration.
Weight is the force exerted on an object due to gravity. It is calculated using the formula:
Weight = mass x acceleration due to gravity
On the Moon, we are given that the weight of the rock is 0.85 N and the acceleration due to gravity is 1.7 m/s^2. Since weight is a force, it is measured in Newtons (N). In this case, the weight represents the force exerted by the Moon's gravity.
To find the mass of the rock, we can rearrange the formula and solve for mass:
Weight = mass x acceleration due to gravity
Dividing both sides of the equation by the acceleration due to gravity:
mass = Weight / acceleration due to gravity
mass = 0.85 N / 1.7 m/s^2
mass = 0.5 kg
Now that we know the mass, we can find the weight of the rock on Earth using the same formula:
Weight = mass x acceleration due to gravity
The acceleration due to gravity on Earth is approximately 9.8 m/s^2. Substituting the values, we get:
Weight = 0.5 kg x 9.8 m/s^2
Weight ≈ 4.9 N
Therefore, the weight of the rock on Earth would be approximately 4.9 N.
