Aconical pendulum is formed by attaching a ball of mass 500 g to a string of length 1.00 m, then allowing the ball to move in a horizontal circle of radius 20.0 cm. (a) find an expression for the tension t in the string. (b) find an expression for the ball's angular speed ? , (c) what is the tension for a 500 g ball swinging in a 20-cm-radius circle at the end of a 10-m-long string (5.00 n)? (d) what is angular speed (in rpm) of a 500 g ball swinging in a 20-cm-radius circle at the end of a 1.0-m-long string (30.2 rpm)? * includes description of the key aspects of the problem and a properly annotated diagram * full algebraic solution included. if necessary, must include diagrams and or graphs to show calculations of important quantities. must have easy to follow steps from beginning to end.
