Weight of object on earth = 49kgf
Therefore, force = 490N
Acceleration = 9.8N/kg
Force = mass × acceleration
Therefore, mass = Force / acceleration
= 490 / 9.8
= 50kg
Now, on another planet:
Mass = 50kg
Force = 40.5N
Force = mass × acceleration
Therefore, acceleration = Force / mass
= 40.5 / 50
= 0.81 N/kg
Hope you found this helpful, cheers :)
