a woman who weighs 150 lb. on earth would weigh 340 lb. on another planet, what is her mass on earth, what is her mass on the other planet, what is the magnitude of the gravitational field on the other planet

Mass does not change with g, weight does.

You seem to be using feet/pounds units so
g = 32 ft/s^2 approx on earth

Mass = 150 /32 slugs

g other = 32 * (34/15)

To find the woman's mass on Earth, we need to use the equation: weight = mass x gravitational acceleration.

The weight on Earth is given as 150 lb., which we can convert to Newtons (the unit of force) since it is more commonly used in physics. 1 lb. is approximately equal to 4.45 N, so 150 lb. would be 150 x 4.45 N = 667.5 N.

The gravitational acceleration on Earth is approximately 9.8 m/s².

Using the equation weight = mass x gravitational acceleration, we can rearrange it to solve for mass: mass = weight / gravitational acceleration.

Plugging in the values, we have: mass = 667.5 N / 9.8 m/s² ≈ 68 kg.

Therefore, the woman's mass on Earth is approximately 68 kg.

To find the woman's mass on the other planet, we can use the given weight on that planet (340 lb. or around 1516.3 N) and the gravitational acceleration of that planet.

Using the equation mass = weight / gravitational acceleration once again, we can rearrange it to solve for mass.

Let's assume the gravitational acceleration on the other planet is called "g₂".

Now we have: mass = 1516.3 N / g₂.

Unfortunately, we don't have the value of "g₂" (gravitational acceleration on the other planet), so we cannot determine the exact mass on the other planet without that information.

However, we can calculate the magnitude of the gravitational field on the other planet by using the equation weight = mass x gravitational field. The weight on that planet is 1516.3 N (given), and the woman's mass on Earth is 68 kg (calculated earlier).

Using the equation weight = mass x gravitational field, we can rearrange it to solve for the gravitational field: gravitational field = weight / mass.

Plugging in the values, we have: gravitational field = 1516.3 N / 68 kg ≈ 22.3 N/kg.

Therefore, the magnitude of the gravitational field on the other planet is approximately 22.3 N/kg.
