The following system is released from rest. The surface is rough with a coefficient of kinetic friction of 0.2. The ramp is 30°. It turns out that the mass M slides down the ramp and 5 seconds elapse. Consider both masses as a single system. M = 8 kg uk = 0.2 m = 2 kg 30° Question 1 1 pts Is gravity on the masses internal or external to the system? internal external Question 2 1 pts Is friction...
3. A bandage is made up of two identical patches of equal mass M, linked by a vis- coelastic material, which we model with springs and dashpots. The bandage is fixed on the two ends. f(t) is the forced applied to the first mass, k is the spring constant and b is the damping coefficient. f(t) a) Draw the free-body diagram for both masses. (b) Describe the system by a set of ordinary differential equations. (c) Find the transfer function...
1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...

We have two very long wires, which are parallel to each other pointing to the right in front of us. The pair of wire is horizontal. The wire closest to us carries a charge per unit length of 1mC/m and the other the opposite charge. The two wires are 1m apart and both move together at 100m/s along the wire to the right. We are looking at what happens in the middle region of the two wires (not the end)....

Question 6.3
6.3 Consider a double mass-spring system with two masses of M and m on a frictionless surface, as shown in Figure 6.30. Mass m is connected to M by a spring of constant k and rest length lo. Mass M is connected to a fixed wall by a spring of constant k and rest length lo and a damper with constant b. Find the equations of motion of each mass. (HINT: See Tutorial 2.1.) risto M wa ww...
Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coefficient of kinetic friction between the...
