A body of mass `1kg` is kept at rest. A constant force of `6.0 N` starts acting on it. Find the time taken by the body to move through a distance of `12 m`.

Explanation

Here, `m=1kg, u=0, F=6.0N, s= 12cm, t=?`
From `F=ma, a=F/m=(6.0)/1= 6m//s^(2)`
From `s= ut+1/2at^(2), 12=0+1/2xx6t^(2)= 3t^(2)` or `t^(2)= 12/3= 4,t=sqrt(4)= 2s`
