Question

A certain object weight 300N at the earth's surface Determine the mass of the object in kg and it's weight in Newton when located on a planet with an acceleration of gravity equal to 4.0ft/s²

Answer 1

We are given:

Weight on Earth = 300 N

Value of g on the planet = 4 ft/s²

Converting to m/s:

4 ft/s² * (1 m / 3.3 ft) = 13.2 m/s²

Mass of the object:

We know that:

Weight = Mass * g

replacing the given values

300 = Mass * 9.8 [g = 9.8 m/s²]

Mass = 300/9.8

Mass = 30.6 kg (approx

Weight on the other Planet:

Weight = Mass * g(on that planet)

Weight = 30.6 kg * 13.2 m/s²

Weight = 403.92 N
