If increase in linear momentum of a body is $50\%$, then change in its kinetic energy is

A body is suspended from a smooth horizontal nail by a string of length $0.25$ metre. What minimum horizontal velocity should be given to it in the lowest position so that it may move in a complete vertical circle with the nail at the centre?

When the kinetic energy of a body executing S.H.M. is $1/3$ of the potential energy. The displacement of the body is $ x $ percent of the amplitude, where $ x $ is:
