Pendulum is released at theta = 90                 we want to know speed at theta = 30                                                                             so the rate of change of speed ,dv/dt = tangential accelration = tangential force/mass                                                                           a = mgsintheta /m      = m ×10 × ½  /m      =5m/s2
