Q. A pendulum consists of a 4.98kg mass on the end of a 0.873 m string. The mass is pulled aside so the string makes an initial angle with the vertical of 12.5o. The mass is then released with initial speed of 2.10m/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:
- speed of the mass: m/s
- magnitude of the tension in the string: N
b) Find the maximum angle between string and vertical?
