One end of an ideal string of length 1.50 m is fixed in space and another end is attached to a particle of mass 2.50 kg. The particle is doing circular motion in a vertical surface, as shown in Fig. 2.1. (a) If the speed of the particle at the top of its path is 7.00 m/s, what are the magnitude and direction of the tension on the particle? If the speed of the particle at point A shown in Fig. 2.1 is also 7.00 m/s, (b) what are the magnitude and direction of the tension on the particle and (c) what are the magnitude and direction of the tangential acceleration of the particle? (d) If the maximum tension that the ideal string can have is 1.20×102 N, what is the maximum speed that the particle can have at the bottom of the path without breaking the string? (e) If the same particle with the same string are doing circular motion as shown in Fig. 2.2, what is the speed of the particle? fig2.jpg
