2. Figure 2 shows a reel of magnetic tape being passed from reel A to reel B with idler pulleys C and D. Calculate the speed of the tape and the total acceleration of the tape at points P1 and P2. Measurements indicate that the normal component of acceleration at P1 is 40 m/s and the tangential component of acceleration at P2 is 30 m/s2. {ans: vel = 2m/s, P1 acceleration = 50 m/s2, P2 acceleration = 85.4 m/s2} P 2 50 mm C D P1 100 mm A B Figure 2: Magnetic tape reel
