The open loop response, that is the speed of the motor to a voltage input of 20 V, assuming a system without damping is 20=(0.02) dw/dt +0.06w Given the initial speed is zero ( ). b) Analogy the above system to an object falling from rest in air, if the air resistive force is proportional to velocity, write a differential equation to represent the motion.

    s(t) = 1/2 g*t^2 - c*s'(t) where g is the acceleration due to gravity, c is the co-efficient of air resistance, s is distance, t is time

    s(t) is the distance function w.r. to time and normally without frictional factors s(t) = 1/2g*t^2 which is the freefall physics equation have you seen this before?
