Figure below shows a conical pendulum, in which the small mass (m = 0.04 kg) at the end of the cord moves in a horizontal circle (radius r = 0.15 m) at constant speed. The cord sweeps out the cone as the mass rotates. The cord has length L = 0.9 m and its mass is negligible. A. Draw a free-body force diagram for the small mass. X b. What is the tension in the cord and the centripetal acceleration of the mass? Ty - my = 0 TO FIND of : cus ods T= 0.04 x 9. P TX = Ma a = -= 167 /52 What is the period of the motion (time of one revolution)? a = rat = 27/ 1.67 = 1.95
