Andee has a mass of 68.5 kg on earth. What is his weight on Earth? What should his mass be in order to have the same weight at the surface of the moon?

W = mg

W = (68.5 kg) (9.8 m/s^2)
W = 671 N

m = W/g
m = 671N/9.8 m/s^2
m = 68.5 kg

Lols. Not really sure about the answer on the mass because there's no given gravity of the moon.

weight (force) = mg

Look up g if you don't know it.

Now, divide that by the relative gravity of the moon. For example, if the moon has 1/2 the gravity of earth, you will need double the mass for the same weight.

I have this assignment too right now,and can't answer it..because the gravity of earth in the moon is not given:(

Answer is lanny

671.3=w on Earth

M=w/g
=671.3N/1.6m/s2
m=419.5652= mass in the moon
W=mg (419.5652)(1.6)
W=671.3 N weight in the moon

To find Andee's weight on Earth, you can use the formula:

Weight = Mass x Acceleration due to Gravity

The acceleration due to gravity on Earth is approximately 9.8 m/s^2. So, substituting the given values:

Weight on Earth = 68.5 kg x 9.8 m/s^2 = 670.3 N

Therefore, Andee's weight on Earth is approximately 670.3 Newtons.

To find Andee's mass on the moon, you can use the same formula. However, since the acceleration due to gravity on the moon is different, we need to find the moon's gravitational acceleration first.

The acceleration due to gravity on the moon is approximately 1.6 m/s^2. So, we can set up the equation:

Weight on Moon = Mass x Acceleration due to Moon's Gravity

We know that Andee's weight on the moon is the same as his weight on Earth, which is 670.3 N. Substituting the values:

670.3 N = Mass x 1.6 m/s^2

Solving for Mass:

Mass = 670.3 N / 1.6 m/s^2

Mass ≈ 419.4 kg

Therefore, in order to have the same weight on the surface of the moon as on Earth, Andee's mass should be approximately 419.4 kg.
