Question

Which would require a greater force. Accelerating 3kg mass at 706cm\sec square OR 6 kg at 300cm\sec square?

Answer 1

Answer:

The first is answer

Explanation:

F=MA

And you know the math, convert cm/s/s to m/s/s.

Answer 2

Answer:

The object of 3 kg of mass requires a greater force

Explanation:

Because,

Momentum of first object of 3kg of mass = 3 * 706

(as p = m.v) = 2118 kg cm /s

Momentum of second object = 6 * 300

= 1800 kg cm /s

So, momentum of first object is greater than second object. Therefore, first object of mass 3 kg requires greater force...
