Consider a system of three masses, each with mass m, joined by ideal, massless springs, each with spring's constant k, as shown in figure 1. k m X1 k m x2 k m x3 k Figure 1: 3 identical masses attached with identical ideal, massless springs. The coordi- nates x₁, x2, x3 represent the position in time of each of the masses. Neglect any effect due to gravity. (a) Show the spring forces acting upon each mass when T1, T2, T3 > 0. (b) Find the equations of motion of each mass. That is, a system of second order, coupled differential equations for x1, x2, x3. (c) Find the normal modes of the system and their associated angular frequencies.

Please answer quick you are in a bumper car with a total mass of 200.0kg your friend is also in a bumper car with a total mass of 200.0kg.You are moving to the right at 1.00m/s. Your friend is moving to the left at 0.500m/s. Your car hits a spot on your friends car that has no bumper. Your bumper acts as a spring with a spring constant of 2.00x10^4N/m. Determine the velocity of your car when the bumper has raced a maximum compression of 0.0700m.Assume friction is negligible.

It is important to say that the dimensions are given in millimeters and tensions are NOT in compression In the system shown, note that a force P (t) is applied at C. Bar ABCD is of negligible mass. Determine: The differential equation of the system. The exercise is shown in the attached image
You are moving to a new place and to go faster, you are pushing with a force P, two boxes at the same time. Your homogenous box 1, on the top has dimensions I₁=1.5m, h₁= 1.6m and a mass of m₁=12kg Your homogenous box 2, on the top has dimensions 1₂=2.4m, h₂= 2.8m and a mass of m2=19kg The coefficient of static friction between the 2 boxes is $12 = 0.34. The coefficient of static friction between box 2 and the ground is SG2 =0.25. Analyze the 4 scenarios: • Box 1 tips on box 2. • Box 1 slides on box 2. .
