A 90-kilogram physics student would weigh 2970 Newtons on the surface of planet X. What is the magnitude of the acceleration due to gravity on the surface of planet X?



Answer :

AL2006
Weight = (mass) x (acceleration of gravity)

Divide each side by (mass),and we have

                     Acceleration of gravity = (weight) / (mass)

Acceleration of gravity = 2,970/90 = 33 newtons per kilogram = 33 m/s²
