Question
please help with both parts and i will rate! thank you!
You work at a garden store for the summer. You lift a bag of fertilizer with a force of 137 M, and it moves upward with an acceleration of 0.816 m/s^2. What Is the mass of the fertilizer bag? How much does the fertilizer bag weigh? Suppose the mass of a fully loaded module In which astronauts take off from the Moon Is 13, 800 kg. The thrust of its engines is 31, 500 N. (Assume that the gravitational acceleration on the Moon is 1.67 m/s^2.) Calculate (in m/s^2) its magnitude of acceleration In a vertical takeoff from the Moon. Could It lift off from Earth? If not. why not? No the thrust of the module's engines is less than its weight on Earth. No, the thrust of the module s engines is equal to its weight on Earth. Yes, the thrust of the module's engines Is equal to its weight on Earth. Yes, the thrust of the module's engines is greater than its weight on Earth. If it could, calculate (in m/s^2} the magnitude of its acceleration. (If not, enter NONE.)Explanation / Answer
mass of fertilizer bag is
F- mg = ma
F= m (g+a)
m = F/ (g+a) = 137 / (9.8+0.816) = 12.9kg
weight of the fertilizer bag is
W= mg = (12.9) (9,8) = 126.5 N = approx 127 N
2)
Acceleration is
a = (31500 - 13800 (1.67)) / 13800 = 0.613 m/s^2
on earth the weight of the module is
W = 13800 (9.8) = 135240. This value is much higher than the thrust applied so it is not possible.
No, The thrust of the engine is less than the weight of the module
None
