A block of mass 10 kg lies to the left of a 5 kg block. The 10 kg block is pushed with a force of 30 Newtons at an angle of 30 degrees South of East (i.e. from the upper left to the lower right of the page).
(a) Draw free-body diagrams for the 10 kg mass, the 5 kg mass, and the system as a whole.
(b) Determine the net acceleration of the system.
(c) Find the contact force (magnitude and direction) of the 5 kg mass on the 10 kg mass.
