The following function V(s) is the Laplace Transform of a voltage waveform v(t), V(s)=\frac{V_{m}}{s^{2} R C(1+s R C)} where Vm is a voltage, R is a resistance and C is a capacitance. a) Express V(s) in partial fractions. Check your answer and verify that the units areconsistent. (b) Based on the partial fraction expansion you derived in 2a, write a time-domain expression for v(t). Check your answer and verify that the units are consistent.
