An оbject аttаched tо the end оf а string swings in a vertical circle ( R=1.20 m), as shown. At an instant when θ=30.00°, the speed of the object is 5.10 ms and the tension in the string has a magnitude of 20.00 N. (a) What is the mass of the object and (b) what are the magnitude and direction of the tangential acceleration of the object? If the speed of the object is 5.10 ms at an instant when θ=0.00°, (c) what is the magnitude of the tension in the string? If the magnitude of the tension in the string is 20.00 N at an instant when θ=270.00°, (d) what is the speed of the object? If the same particle with the same string is doing circular motion as shown in Fig. 2.2, (e) what is the speed of the particle?
