Given a system with input x(t) and output y(t) is described by the differential equation: d3y(t)/dt3 + 7d2y(t)/dt2 + 12dy(t)/dt = dx(t)/dt + 4x(t) a. Find the transfer function H(s) and the impulse response, h(t) where Y(s)=H(s)X(s) b. Find the respo
How much time after engine failure will elapse before the rocket comes crashing down to the launch pad?
1.) Differentiate EN with respect to r, and then set the resulting expression equal to zero, because the curve of EN versus r is a minimum at E0. 2.) Solve for r in terms of A, B, and n, which yields r0, the equilibrium interionic spacing.
