Question

On a planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 10kg weighs 80 N. Calculate the weight of an object whose mass is 3 kg.

Answer 1

`f = mg\\ 80 = 10g \\ g = 8 \: m .{s}^( - 2) \\ w = 3 * 8 = 24 \: newton \\ \: on \: that \: planet`
