Which would require a greater force for accelerating a 2 kg of mass at `4 ms^(-2)` or a 3 kg mass at `2 ms^(-2)` ?

Text Solution

Verified by Experts

We know force F = ma
given `m_(1) = 2 kg, a_(1) = 4ms^(-2)`
`m_(2) = 3kg, a_(2) = 2 ms^(-2)`
`F_(1) = m_(1)a_(1) = 2xx4 = 8N`
`F_(2) = m_(2)a_(2) = 3xx2 = 6N`
`therefore F_(1) gt F_(2)`
Thus, accelerating 2 kg mass at `4 ms^(-2)` would require a greater force.
