Question

What would require a greater force acceleration a 2kg mass at 5m/s or a 4kg mass at 2m/s

Answer 1

According to Force Formula

Force = Mass×Acceleration

For 1St Once

Mass = 2KG

Acceleration = 5M/Sec²

Force = MA

Force = 2×5
= 10N

For Second

Mass = 4KG

Acceleration = 2M/Sec²

Force = MA

Force = 4×2
= 8N

The First One Requires More Force.

Answer 2

2kg mass at 5m/s would require 10m/s^2 of force

4kg mass at 2m/s would require 8m/s^2 of force

So, 2kg at 5m/s requires more force
