The direction of motion of a flat tape in a numerical-control device is changed by the two pulleys A and B shown. If the speed of the tape increases uniformly from 1.7 m/s to 15.9 m/s while 7.7 meters of tape pass over the pulleys, calculate the magnitude of the acceleration of point P on the tape in contact with pulley B at the instant when the tape speed is 4.2 m/s. Part 1 150 mm 225 mm B Find the tangential component of acceleration of the tape. Answer: 0₂-1 m/s²
