Which would require a greater force-accelerating a 2kg mass at 5 m `s^(-2)` or a 4kg mass at 2 m`s^(-2)`?

Text Solution

Verified by Experts

Here, F=ma
`m_(1)=2kg,a_(1)=5 ms^(-2)` and
`m_(2)=4kg,a_(2)=2 ms^(-2)`
This,`F-(1)=m_(1)a_(1)=2kgxx5 ms^(-2)`=10 N and
`F_(2)=m_(2)a_(2)=4kgxx2ms^(-2)=8N`
`impliesF_(1)F_(2)`
Thus accelerating a 2 kg mass at 5 m`s^(-2)`
Would require a greate force.
