Kinetic, as inertia means to remain unchanged.
For the gravitational force the formula<span> is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s</span>2<span> at the surface of the earth) and h is the </span>height<span> in meters. Notice that gravitational potential </span>energy<span> has the same units as </span>kinetic energy, kg m2<span> / s</span>2<span>.

Answer:4kg
Explanation:
acceleration due to gravity(g)=10m/s^2
Weight(w)=40N
Weight=mass x g
40=mass x 10
Divide both sides by 10
Mass =40/10
Mass=4kg
