If a force accelerates at 4kg at 2 m/s, by how much would the same force accelerate 16kg

Explanation:

f=m*a → f=4*2 = 8 kN

f=m2 * a2 → 8=16*a2

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

this is a good question! i'll do some research and come back when i have the answer!
