Elastic unequal mass collision: We have a similar situation as in the previous question but now truck A has mass mA and initial velocity uA. Truck B has mass mB and is initially at rest. The collision is elastic. (a) Show the subsequent velocities vA, vB in the laboratory frame are: vA = (mA − mB)uA/(mA + mB), vB = 2mAuA/(mA + mB). On the basis of these results, find the velocities in the two limiting cases: (i) mA >> mB; (ii) mA << mB. (b) Find the subsequent initial and final velocities u′ A, u′ B and v′ A, v′ B in the CM Frame

A hydroelectric with 0.2 m radius coils has permanent magnets that immerse the coils in a magnetic field of 0.5 T. If the maximum torque that the turbines can produce is 750 Nm and it is sought to generate a maximum voltage of V = (1414.3 V) sin (wt) at an average rms power of 2x10 ^ 4 W. a) What maximum current the turbine should generate, b) how many turns should the coil have, c) what radius should the coil cable have? d) if it is to be transported at 50 kvrms, how many turns should the secondary inductor of the transformer have for each turn of the primary?

2) Imagine an infinitely long hollow metal pipe with a rectangular cross section. The four sides are placed at x = −a and x = a, and at y = −b and y = b. The two sides on the x-axis (and parallel to the y-z plane) are held at V = 0, the two sides on the y-axis (and parallel to the x-z plane) are held at a constant positive potential V = V0. Imagine that each infinite plate is separated from each adjacent plate by a thin insulation. Find the potential inside the wire.(Please be as detailed as possible with the derivations and steps associated with solving the problem, (please and thank you!!).
