Question

# A body of mass 'm' is travelling with a velocity 'u'. When a constant retarding force 'F' is applied, it comes to rest after travelling a distance 's '. If the initial velocity is ( ^{prime} 2 u^{prime}, ) with the same force 'F', the distance travelled before it comes to rest is 's ( _{2}^{prime} . ) Then(A) ( mathrm{s}_{2}=2 mathrm{s}_{1} )(B) ( s_{2}=frac{s_{1}}{2} )( (mathrm{C}) mathrm{s}_{2}=mathrm{s}_{1} )( (mathrm{D}) mathrm{s}_{2}=4 mathrm{s}_{1} )
