One end of an ideal string of length 0.800 m is fixed in space and another end is attached to a particle. 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/x and the tension of the string is 26.0 N, what is the mass of 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 tensions 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 50.0 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? Fig. 2.1 top 30.0⁰ Fig. 2.2 0.800 m 30.0⁰
