A m₂ = 12 kg B (a) (3 marks) Write down the momentum vectors for each block. 50° 40° mg = 7 kg Va = 16 m/s Two blocks collide on a horizontal, frictionless surface. The velocities and masses of both blocks are shown in the diagram above. Note that the view is one looking down on the blocks, i.e., the +z axis is coming out of the page. VA = 12 m/s (b) (4 marks) After colliding, the blocks stick together, forming a combined block. What is the resulting momentum vector of the new combined block? (e) (4 marks) How far does the combined block travel before it stops? (c) (2 marks) What is the normal force exerted by the floor on the new combined block? (d) (4 marks) The combined block now crosses over onto a rough surface with kinetic friction coefficient μ = 0.32. How long does it take to come to a complete stop? (f) (3 marks) You find you have to apply a horizontal force of magnitude 65 N to get the combined block moving again on the rough surface. What is the static friction coefficient, us, of the rough surface?
