Find the least horizontal speed with which it projected

Reference no: EM13670868

A particle of mass 3 kilogram is attached to the end of a string of length 4 meter, whose other end is fixed. Evaluate the least horizontal speed with which it must be projected from the lowest point, if it is to describe complete vertical circles. Determine also the tension in the string at the instant of projection.
