one question: During each cycle, the velocity v (in mm/s) of a piston is v = 6t - 6t^2, where t is the time (in sec). Find the displacement s of the piston after 0.75 sec if the initial displacement is zero.
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
