Question

A car begins to move at time t = 0 and then accelerates along a straight track with a velocity  given by V(t) = 2t2 ms–1 for 0 < t < 2, where t is time in second. After the end of acceleration, the car continues to move at a constant speed. A small block initially at rest on the floor of the car begins to slip at t = 1 s and stops slipping at t = 3 s. The coefficient of static and kinetic friction between the block and the floor are μs and μk respectively. Find the value of .
