Question

The upper end of the string of a simple pendulum is fixed to a
vertical z-axis, and set in motion such that the bob moves along a
horizontal circular path of radius 2m parallel to xy plane 5 m
above the origin the bob has a speed of 3 m/s the string breaks
when bob is vertically above the x axis and is vertically above the
x axis , and it lands on the xy palne at point

In the question, when string breaks the particle starts from the
point (2,0,5) with speed uy=2 m/s and moves as a projectile
It will reach the xy plane in 1 second
