Question

This diagram shows a rubber bung, of mass 200 g, on the end of a length of string being swung in a horizontal circle of radius 40 cm. The string makes an angle of 56° with the vertical.

Calculate:
i the tension in the string
ii the angular speed of the bung
iii the time it takes to make one complete revolution​

Answer 1

Answer:

Length of conical pendulum = l = 5.0 m, radius of circular path of ... mass of bob = m = 100 g = 0.1 kg, radius of circle = r = 30 cm = 0.3 m, g = 9.8 m/s2,.
