A woman has a mass of 42.9 kg. What is her weight on earth? and what is her weight on the moon, where g=1.17 m/s2
g = 9.8m/(s^2) *acceleration due to gravity on earth*
therefore:
W,earth = mg = 42.9*9.8 = 420.42 N = 420. N (if significant figures must be checked)
W,moon = mg = 42.9*1.17 = 50.2 N
so there,, :)
To find the woman's weight on Earth, we need to multiply her mass by the acceleration due to gravity on Earth.
The acceleration due to gravity on Earth is approximately 9.8 m/s^2. So, her weight on Earth can be calculated using the formula:
Weight on Earth = Mass × Acceleration due to gravity on Earth
Weight on Earth = 42.9 kg × 9.8 m/s^2
Weight on Earth = 419.42 N
The woman's weight on Earth is approximately 419.42 Newtons.
To calculate her weight on the moon, where the acceleration due to gravity (g) is 1.17 m/s^2, we can use the same formula but substitute the value of g for the moon:
Weight on the Moon = Mass × Acceleration due to gravity on the Moon
Weight on the Moon = 42.9 kg × 1.17 m/s^2
Weight on the Moon = 50.19 N
The woman's weight on the moon is approximately 50.19 Newtons.
