Please explain with detail Mass on a String

An object of mass M on a string is whirled with increasing speed in a horizontal circle with the help of a string. When the string breaks, the object has speed $v_o$ and the circular path has radius R and is a height h above the ground. Neglect air friction. Determine the following, expressing all answers in terms of h$,$ vo$,$ and g$.$

a$)$ The time required for the object to hit the ground after the string breaks.

b$)$ Horizontal distance the object travels from the time the string breaks until it hits the ground.

c$)$ The speed of the object just before it hits the ground.

d$)$ Determine the tension in the string just before the string breaks. Express your answer in terms of M$,R,v_o,$&$g$
