A large carrdboard box of mass 0.75kg is pushed across a horizontal floor by a force of 4.5N the motion of the box is opposed by i) frictional force of 1.5N between the box and the floor and ii) an air resistance force kv^2 6.0*10^-2kg/m and v is the speed of the box in metres .sketch a diagram showing the directions of the forces acting on the moving box. calculate the minimum values for a) the acceleration of the box b) the speed of the box

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
