Answer:
<u>See Below for explanation and answers</u>
Explanation:
We are going to solve these problems using the formula:
W = mg
Where
W is weight in Newtons (N)
m is mass in (kg)
g is acceleration due to gravity
g on earth is 9.8 m/s^2
So,
<u>Weight on Earth = mg = 45 * 9.8 = 441 N</u>
Mass doesn't change, so on Jupiter, Felicia's mass would be same.
<u>Mass on Jupiter = 45 kg</u>
The weight on Jupiter would change because of g changing to 25, so
<u>Weight on Jupiter = mg = 45 * 25 = 1125 N</u>
<u></u>
Moon's g is 1/6th of earth, so it would be:
Moon g = (1/6)*9.8 = 1.63
Now,
On earth weight of backpack = mg = 1760
On moon weight would be = m(1/6 g) = 1760/6 = 293.33 N
A) <u>Backpack Weight on Moon = 293.33 N</u>
On moon, the mass would be same as earth, so lets calculate:
W = mg
293.33 = m (1.63)
m = 179.96 kg
B) <u>Mass of Backpack on Moon = 179.96 kg</u>
<u></u>
Taking he is on earth with a weight of 1150 Newtons, his mass would be:
W = mg
1150 = m(9.8)
m = 117.35 kg
<u>Mass = 117.35 kg</u>
<u>Weight = 1150 N</u>
<u></u>
g is Mars is 3.7
Weight on earth is 64 N
the g of Mars is of the g on earth, so weight would go down by that factor.
<u>Weight of Melon on Mars = 64 * 0.38 = 24.32 N</u>
<u></u>
The mass would be (on Mars):
W = mg
24.32 = m (3.7)
m = 6.57 kg
<u>Mass of Melon on Mars = 6.57 kg</u>
