JEE Advanced 2020 Concept Recapitulation Test 4 Paper 2

A box of mass 1kg is lying on a rough horizontal floor and a horizontal force acting on box has a magnitude of F=3t2N, where t is in seconds. If the box starts from rest, determine its speed (in m∕s ) at t=3 second. The coefficient of static and kinetic friction between the box and horizontal floor are µs=0.3 and µk=0.2
