A 0.5 kg ball traveling at 1 m/s to the right hits a second ball of equal mass that is initially at rest. After the perfectly el
astic collision, the second ball travels at 0.543 m/s at a 57.2 degree angle upward from the point of contact.

Answer
given,
Tension of string is F
velocity is increased and the radius is not changed.
the string makes two complete revolutions every second
consider the centrifugal force acting on the stone
=
now centrifugal force is balanced by tension
T =
From the above expression we can clearly see that tension is directly proportional to velocity and inversely proportional to radius.
When radius is not changing velocity is increasing means tension will also increase in the string.
