More mass, more inertia, less speed, more momentum because momentum is depends its mass and speed. Hope it helps

remember
reactants ----> products
The solution for this problem is:
If they feel 50% of their weight that means that the
centripetal force is also 50% of their weight 1g - 0.5g = 0.5g
Then 0.5* 9.8m/s² * 18m = 88.2 would be v²
Then get the square root, the answer would be:
and v = 9.391 m/s is the answer.
Value of resistor = (12V) /(1.2 x 10^-3A)=10000ohms=10k ohms
