Homework H.6.N Given: Cart A (of mass m) is supported by two rollers C and D each of mass m, and having outer radii of Rand 2R, respectively). The rollers are known to roll without slipping with respect to both the ground and cart A. A spring of stiffness k is attached between the left side of the cart and ground. Two additional springs, of stiffnesses k and 2k, are attached between the right side of cart A and a moveable base B. The base B is given a prescribed motion of r(t)=b cost. Let represent the motion of cart A, where x = x =0 when all three of the springs are unstretched. Find: For this problem: (a) Derive the differential equation of motion (EOM) for the structure in terms of the coordinate (b) Identify the natural frequency wn of oscillations for the system; (c) Derive the particular solution for the EOM, xp(t); and, (d) What is the amplitude of the motion for the cart when 2 = 2wn? Is the cart moving in-phase or out-of-phase with the base B at this frequency of excitation? XBO 2k w w w D 2R 1 cm no slip m )

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
