Solve for number 2 only

... Try these Take g = 9.8 ms? 2 kg la A parcel of mass 2 kg lies at rest on a rough horizontal surface, as shown. i Draw a force diagram showing the forces acting on the parcel. ii Calculate the normal contact force, R. b The parcel is now pushed with a horizontal force P, as shown, so that it is just on the point of sliding. i Draw a force diagram showing the forces now acting on the parcel. ii If the coefficient of friction is 0.5, find the value of P when the parcel is on the point of sliding. 40 N 2 A dustbin of mass 12 kg standing on horizontal ground is pushed by a horizontal force of 40 N. 12 kg If the coefficient of friction is 0.4, will the dustbin move?
