An observer and a vehide both start moving together from rest towards right with acceleration 1 m s and 2 m s respectively There is a 1 kg block on t floor of the vehide and coefficient of friction between their surface is 0 1 What is the magnitude of the work done in J by frictional force on the 1 kg block observed by the running observer during first second of the motion 1kg 2 m s 1 m s
