-(b÷2)=-3
b=-2×-3=+6
=> b=6
Weight is another term for the force from mass multiplied by acceleration due to gravity, the equation being expressed as

, being force, mass, and acceleration respectively.
We already have 2 parts of the equation,
Acceleration due to gravity on the planet is

Plug it into the equation


x

Weight or force from gravity is 60N.
