3. Magnetic tape is being transferred from reel A to reel B and passes around idler pulleys C and D.At a certain instant, point P1 on the tape is in contact with pulley C and point P2 is in contactwith pulley D. If the normal component of acceleration of P1 is 40 m/s2 and the tangentialcomponent of acceleration of P2 is 30 m/s2 at this instant, compute the corresponding speed ofthe tape, the magnitude of the total acceleration of P1 and the magnitude of the totalacceleration of P2.P, 50 mm100 mmA.
