Two blocks are in contact on a table with kinetic friction coefficient of 0.2.A horizontal force is applied to the larger block, as shown in Figure. (a) If m1 2.3 kg, m2 =1.2kg, and F#3.2N, find the magnitude of the force between the two blocks.

An experiment is done on a horizontal surface. A block of mass m_1 is initially held in place compressing a spring with spring constant k by a distance x_0. The other end of the spring is firmly attached to the wall and does not move. What is the final speed of m_1 after it is released and loses contact with the spring? After it reaches its final speed, m_1 collides and sticks to a second block of mass m_2. What...

A block of mass m_1 = 1.5 kg is placed on a horizontal surface. Attached to the block is a string which passes over a pulley and suspends a mass m_2 = 3.5 kg as shown in the diagram below. If the system accelerates at a = 5.2 m/s^2, what is the coefficient of kinetic friction mu_k between the horizontal surface and m_1?

A pulley system is attached securely to the corner of a ceiling and connects to masses M_1 and M_3 as shown. Under M_3 sits another mass, M_2. Mass M_1 rests on a 65 degree incline, while masses M_2 and M_3 are on a 23 degree incline. The coefficient of kinetic friction between the masses and the inclines is mu _k = 0.10, while the coefficient of static friction between M_2 and M_3 is mu _s = 0.90. If M_2 =...

A small block of mass m is at rest on a table. The coefficient of friction between the block and the table is mu. (The coefficient of static friction is equal to the coefficient of kinetic friction in this problem.) A horizontal force is applied at t = 0 which has magnitude beta t where beta is a known constant. Find the block's velocity as a function of time. Free Body Diagrams (If appropriate). Law or Definition
