Three blocks with masses, m1 = 1 kg, m2 = 2 kg, and m3 = 4.0 kg, are pulled to the right across a horizontal frictionless surface by a constant force, F = 48 N, that acts on the large block as shown in the figure. Two of the blocks, m1 and m3, are connected by an ideal rope while the smallest block, m2, is sitting directly in front of m1 as shown. Take right as the positive direction. Version One. (a) Find the acceleration of the system? m/s2 (b) Determine the magnitude of the tension in the rope between m1 and m3. N (c) What is the magnitude of the normal (contact) force between m1 and m2 ? N Version Two. What if block m2 was placed on top of block m1 instead of in front of it? (a) What would be the acceleration of the system and tension in the rope if m2 and m1 stuck together? a = m/s2 T = N (b) What if the blocks were made of ice so that m2 and m1 didn't stick together? At what rate would each block accelerate? a1 = m/s2 a2 = m/s2 a3 = m/s2 a3 = What would be the tension in the rope?

Shown in the figure below is a magazine resting on top of a book. There is static friction between the magazine and the book and there is kinetic friction between the book and the table. If you pull very gently on the book, both objects slide together. If you pull very forcefully, you will slide the book out from under the magazine. In this problem, we will determine the MAXIMUM FORCE that you can apply and still have the magazine come along for the ride. The characteristics of the system are given here: m1 = 0.35 kg m2 = 1.01 kg μs = 0.33 μk = 0.22 Answer all the following: What is the normal force, N1, of the book on the magazine? N What is the normal force, N2, of the table on the book? N What is the acceleration, a of the system? m/s2 What is the force applied, Fmax? N
