A 500 g small mass on the end of a 1 50 m long
A 500-g (small) mass on the end of a 1.50-m-long string is pulled aside from the vertical and shoved downward (toward the bottom of its motion) with a speed of 2.00 m/s.
(a) Is the angle on the other side (1) greater than, (2) less than, or (3) the same as the angle on the initial side (15o)? Explain in terms of energy.
(b) Calculate the angle it goes to on the other side, neglecting air resistance.
