A pendulum consists of a 1.56 kg mass on the end of a 0.806 m string. The mass is pulled aside so the string makes an initial angle with the vertical of 18.8o. The mass is then released with initial speed of 1.3 m/s upward and perpendicular to the rope. Assume:
- There is no friction anywhere.
- The rope remains taut at all times.
a) When the mass reaches the bottom of its arc, find:
- the speed of the mass: m/s
- the magnitude of the tension in the string: N
b) Find the maximum angle between the string and the vertical:
