Can anyone please give me some idea for this problem? The instantaneous power, p, in an electric circuit is given by p = iv, where v is the voltage and i is the current. Calculate the maximum value of power in the circuit if v=0.02 sin(100 pi t)volts and i=0.6 sin(100pi t+ pi/4 ) amp...

I got part a) w^2=g/h w=3.61 rad s^-1 part b ?

cool. any idea about part b?

I got w^=g/h w=3.61 so far correct?

Hi guys. I need some help to solve this question. (a) A body of mass m kg is attached to a point by string of length 1.25 m. If the mass is rotating in a horizontal circle 0.75 m below the point of attachment, calculate its angular velocity. (b) If the mass rotates on a table, calculate the...
