Answer: A vehicle's capacity to gain speed within a short time...
As momentum / time = force
so; time = 100÷15
so your answer is 6.7 !!
Density =mass/volume
density= (0.044kg/(11 x10^-6)
4000kg/m^3
The question doesn't describe any experiment. If the same experiment is repeated, no matter how many times, the acceleration due to gravity will remain the same as it was during the non-existent original experiment, and will have no effect on anything.
